A polyhedron (polyhedra or polyhedrons if more than one) is a geometrical shape. It is a 3D shape with flat faces, and straight edges. Each face is a polygon surrounded by edges. Usually it is known by the number of faces, corners, or edges it has. 

There are many groups of polyhedra, which can either be only a small set, or can be infinite. Prisms, pyramids, antiprisms, and bipyramids are groups of polyhedra. 

A regular polyhedron has faces that are all the same, corners that are all the same, and edges that are all the same. A uniform polyhedron can have one or two kinds of its parts be all the same.

Definition 
Two types of polyhedron are convex and concave. The edge connecting any two points of a convex polyhedron is inside the polyhedron. The line connecting two points of a concave polyhedron may go outside the polyhedron. The Platonic solids are regular convex polyhedra.
Mathematicians do not always agree on what makes a polyhedron. Some may only consider the convex polyhedra, and disregard the ones that are not convex. Some polyhedra are degenerate, meaning that when drawn as real objects, they look flat.

Naming 
Usually, polyhedra are named by the number of faces they have. The first polyhedra are the tetrahedron, which is made of four triangles, pentahedron (five faces, can look like a four-sided pyramid), hexahedron (six faces, a cube if it is regular), heptahedron (seven faces) and octahedron (eight faces). Prisms, pyramids and other shapes can also be named after how many faces they have.

A pentagon is a polygon with five edges. It is defined by five points, which are all on a plane. If all the edges have the same length and the angles at the corners are all 108°, the pentagon is called regular. If the pentagon intersects itself, it is called a pentagram.

Pentagons also occur in nature: Fruits of the Okra are pentangular. The flowers of Ipomoea are pentagular. In chemistry, many Cyclic compounds are pentangles: Cyclopentane and Furan are examples for this. In architecture, many bastions are pentangular: Bourtange, in the Netherlands has been completely restored, and is a pentangle.  The Citadel of Lille, Nyenschantz, near St. Petersburg, or the Citadel of Pamplona are . The Villa Farnese is a palace in the form of a pentagon, so is the castle of Nowy Wiśnicz. The Pilgrimage Church of Saint John of Nepomuk near Žďár nad Sázavou  also uses a pentangular design.

A Calendar date is a way to refer to a certain day in a calendar. With the calendar date and the calendar, the exact day can be identified. With a different calendar, the same calendar date may refer to a different day. This can be seen easiest when comparing the Julian calendar with the Gregorian calendar. 

Calendar dates are important to refer to events (most holidays are fixed with reference to a particular event or calendar date.) One example may be Easter. In the Middle Ages, it has been fixed that Easter is to be the first Sunday that is (on or after) the 14th day after the spring equinox. 

Most calendar systems have a date format that has three parts, the day of a certain month, the month and the year. Sometimes the week is added.

Calendars
The Iranian calendar  also known as Persian calendar or the Persian Calendar is a Shahanshahi Or King calendar. It is currently used in Iran and Persia. It is observation-based, rather than rule-based. Each year starts on the vernal equinox as precisely determined by astronomical observations from Tehran (or the 52.5°E meridian, which also defines IRST) and Tehran. This makes it more accurate than the Gregorian Calendar.

The current Iranian Calendar year is 2582 AP (AP = Anno Persico/Anno Persarum = Persian year).

A hexagon is a polygon with 6 sides and 6 corners (vertices). Like regular triangles and squares, hexagons fit together without gaps. This is known as a tessellation. Because of this, they are often used for tiling floors. They are also quite common in nature. For example, the honeycombs in a beehive are hexagons.

Ayatollah Sayyid Ahmad Khatami () is a member of the Iranian Assembly of Experts.

Although his name resembles that of Mohammad Khatami, the reformist former president of Iran, the two men are not related.  In fact, they have opposite points of view on many issues, such as democracy and velayate faqih in Iran.

A tendon (or sinew) is a tough band of tissue that connects muscle to bone. It is built to withstand tension. Tendons are similar to ligaments except that ligaments join one bone to another. Tendons and muscles work together, roughly as follows. When muscles contract, the tendon transmits the pull to the bone.

Anatomy 
A tendon connects to a muscle at one end, and to bone at the other end. Each tendon has these two "insertions".

Collagen fibres connect the muscle to the bones. A tendon inserts into bone at one end, and into the muscle at the other end. 

Tendons do not create any pulling force of their own. The tendons transfer the force of muscles pulling on the bone. Unlike elastin (another bodily tissue) tendons have very little "give". 

Tendons are often connected to joints.

Coffee substitutes are products that try to taste like coffee. The idea for using them is to have a drink that tastes like coffee, but has no caffeine in it. The main reasons for making coffee substitutes are medical, economic and barbaric. In World War II, acorns were used to make coffee, however it tasted foul. It was also hard to get. In the American Civil War there was a similar story -

"For the stimulating property to which both tea and coffee owe their chief value, there is unfortunately no substitute; the best we can do is to dilute the little stocks which still remain, and cheat the palate, if we cannot deceive the nerves." The Southern Banner, 1865

Ingredients
Grain coffee and other substitutes can be made by roasting or decocting various organic substances.
Some ingredients used include: almond, acorn, asparagus, barley and malt, beech nut, beetroot, carrot, chicory root, corn, cotton seed, dandelion root, fig, boiled-down molasses, okra seed, pea, persimmon seed, potato peel, rye, sassafras nut, sweet potato.

Chicory has been sold commercially on a large scale since around 1970, and it has become a mainstream product. It was widely used during the American Civil War on both sides. Chicory is a native plant of Western Asia, Europe, and Northern Africa. And the cultivation of the plant is considered to be originated in Egypt. In France, around the 1800s, chicory was used as an ingredient or substitute for coffee.
Postum is an instant type beverage used in place of coffee. It made from roasted grains and molasses. Postum history goes back to 1895 when an American named C.W. Post created the coffee substitute, inspired by a caramel coffee recipe made by Harvey Kellogg. It reached the height of its popularity during World War II. It also really caught on with people who for health or religious reasons preferred not to consume drinks that contained caffeine. For popular usage on the sitcom Seinfeld George says to Jerry he does not know why postum is not a more popular beverage.

The Croatian language is spoken mainly throughout the countries of Croatia and Bosnia and Herzegovina and in the surrounding countries of Europe.
Croatian grammar is the grammar of the Croatian language. The Croatian language consists of three vernaculars (Kaikavian, Chakavian and Shtokavian).
Croatian grammar books show that the codification of the language started at the beginning of the 17th century (the first grammar was written by Bartol Kašić in Latin in 1604). This means that the rules for the language were written down. From 1604 to 1836 there were 17 grammars. Most of them described the Štokavian dialect, but some were about Kajkavian. In the 19th century, more grammars based on Štokavian were written. They were "Nova ricsoslovnica illiricka", written by Šime Starčević (1812), and "Grammatik der illyrischen Sprache", written by Ignjat Alojzije Brlić (1833),. Even before the 19th century, the three dialects of the Croatian language were almost equally used. However, the way each dialect was written down varied throughout Croatia. Near the Adriatic coast, it was more similar to Italian, and near the Hungarian border, it was more similar to Hungarian.
All grammars of the above period (1604-1836) used three accents: acute, grave and circumflex, Starčević's grammar is an exception as it uses a system of four accents.
In 19th century, Ljudevit Gaj proposed new letters from Czech (č,ž,š,ľ,ň,ď and ǧ). The letters that were accepted were č, ž and š, and from Polish, ć. For other phonemes (sounds), the digraphs that were accepted were ie, lj, nj and dž. Later dj or gj was changed to đ (according to proposal by Đuro Daničić).
Orthography 
The Croatian language uses a Latin script of 30 letters and one diphthong "ie" or "ije", and "ŕ". This system is called gajica in Croatian (or Croatian Gaj's Latin alphabet). The name came from Ljudevit Gaj. The letter order (and whole alphabet) is called abeceda in Croatian, because the first 4 letters are spelled "a, be, ce, de". For writing foreign names and words, and in some professions, the Croatian language uses letters which do not belong to gajica, like "X, x (iks), Y,y (ipsilon)" and others.

Croatian alphabet (Gaica) 1830.c
Grammatical cases 
In Croatian, nouns change form depending on the composition of the sentence. This is called declension. For people who are learning Croatian, declension is the most difficult part of the language to master. It is very complicated and time-consuming to explain it and because of that we will use simpler techniques. However, many languages have noun and pronoun declension, including English. In English, though, only pronoun declension now remains. Let us start by explaining all of the seven Croatian grammatical cases. The technique that is most frequently used in determining grammatical cases (the same technique is used in Croatian schools when taught to children) is by asking yourself a question when you are trying to figure out which case a noun should be in. In Croatian, grammatical cases are called padeži (plural) and padež (singular).
 Example:
 In this example you will be shown how to determine a noun's grammatical case by using the table below.
Krešimir is going to school. (Krešimir ide u školu.)
The question you will ask yourself here is: “Where is Krešimir going?”. And the answer is that he's going to school. By looking at the table below you will see that the question 'where' is used for the Locative case.
Gender 
Croatian nouns are divided into three genders: the masculine, feminine and neuter gender. To know a noun's gender is very important because it affects all the words in a sentence that are tied to the noun, such as adjectives. A gender is determined by the noun's ending (with some exceptions). This makes it easier to tell what gender a noun is without memorizing the gender of every word. See the table below.
Nouns retain their gender in plural. For instance, even though the noun 'žene' (women) ends in -e, it is of the feminine gender.

Grammatical aspects 
Croatian verbs have two grammatical aspects: the perfective and imperfective. The perfective aspect depicts an action that has already been finished. The imperfective aspect depicts an action that is still continuing. So, each verb in its infinitive form can be written in 2 ways: in its perfective and imperfective aspect. The table below is showing 5 verbs both in their perfective and imperfective aspects.
Grammatical tenses 
In Croatian, there are seven grammatical tenses. They can be divided in two ways: by the time they take place in and by their complexity. Simple tenses consist of only 1 word (simple tenses are aorist, imperfect, and present) while complex tenses consist of 2 or even 3 words (complex tenses are pluperfect, perfect, first future, second future) because they also consist of auxiliary verbs. Also, some grammatical tenses cannot be formed with both grammatical aspects, they work with only one aspect.

A prize is an award given to a person or a group of people to reward good work. 

Official prizes often include monetary rewards as well as the fame that comes with them. Some prizes are given out in famous ceremonies, such as the Oscars.

Prizes are given for a number of reasons: as an honour for special persons, for exemplary behaviour and to provide incentives in competitions, etc. In general, prizes are regarded in a positive light, and their winners are admired. However, many  prizes, especially the more famous ones, have often caused controversy and jealousy.

Specific types of prizes include:
 First prize, second prize, third prize etc.
 Consolation prize: an award given to those who do not win an event but are deserving of recognition.
 Booby prize: typically awarded as a joke to whoever finished last.
This article is about the universal religious institution. For general information about Christianity or information about specific Christian denominations, see the appropriate page. For other uses, see Church (disambiguation).

The term Christian Church, Catholic Church or One Holy Catholic and Apostolic Church, as it was called by 110 AD, refers to the "universal company of believers". It means every person who has ever accepted or ever will accept the Christian Faith. The idea is that all these people together make up one "body" called "the Church". "The Church" (in this sense) is not thought of by Christians as an ordinary human organisation. It is thought of as being part of God's way to bring people close to him. "The Church" was begun by Jesus in the 1st century AD. It is called "The Christian Church" because Jesus was called "The Christ" (or holy one from God).

Today there are many churches in the sense of "church organisations". The different organised churches are called Christian denominations.
The main Christian beliefs are held by all major Christian denominations. These beliefs are often said aloud by Christian people in a "statement of faith" which is called the Creed. The Roman Catholic, Eastern Orthodox, Oriental Orthodox, Lutheran, Anglican Communion and other Protestant churches all believe that God is the "creator and eternal father of all things", that Jesus was the "Christ" and son of God who died to save people from the punishment for their sins, and that the Holy Spirit is God's gift to help and comfort Christian people. Christians believe that these are three parts of One God.

There are many other beliefs that are different between different denominations. These differences have sometimes caused arguments and have caused the organised church to split into denominations. The different opinions are called controversies.

During Late Antiquity, the Christian Church started became the most important persecuting organization in human history.

Terminology
Terminology 

The English word church comes from the Greek κυριακή (kyriake) meaning "Master's (house)", or "Lord's (house)". In modern English the word "church" is used for both a church building and "the Christian Church" throughout the world.

In 381 AD, at the a meeting of bishops known as the First Council of Constantinople, the Nicene Creed (a statement of beliefs) that was used at the time was changed to include a description of the Church. The words that were added to the Nicene Creed are "One Holy, Catholic and Apostolic Church". This important addition describes the four most important things that Christians were to believe about the Christian Church.
These are the four words that are used in the Nicene Creed: 
 The Church is One. This means that there is only one true Christian Church. It is "universal".
 The Church is Holy. This means that it is the Church of the true and living God.
 The Church is Catholic. This means that the Church includes "everyone" who is a true Christian believer.
 The Church is Apostolic. This means that it was begun by the Twelve apostles of Jesus and that Christian believers follow in their footsteps.

Controversies
Controversies 

One important controversy is simply the definition of the Christian or Catholic Church. To some degree this controversy comes from the Nicene Creed with its words One Holy Catholic and Apostolic Church which means universal church. Many denominations believe that all denominations are part of a world-wide Christian Church and think that the most important thing is the "common faith" and not a common organisation or tradition. ("Common faith" means "the faith that is the same". The word "common" does not mean "ordinary" in this sense.)
For many hundreds of years, the Roman Catholic Church has regarded itself as the only Christian Church and has called itself the Catholic (or "universal") church. In other words, only those people who were within the organisation of the Roman Catholic Church were believed to belong to the Universal Church. In the 20th century this view began to change and in the late 20th century there was a strong movement within parts of the Roman Catholic Church to reach out to other denominations. The Eastern Orthodox Church has thought of itself in the same way, but in the late 20th century there has been much more discussion between the Orthodox Church and Roman Catholic, Lutheran and Anglican Churches. Some smaller denominations such as Jehovah's Witnesses also believe that they are the one and only true Christian Church.

A religious denomination (also simply denomination) is a subgroup within a religion that has a common name, tradition, and identity.

The term is often used for several Christian denominations including Eastern Orthodoxy, Catholicism, and the many sorts of Protestantism like Baptist, Methodist, Episcopalian and Pentecostal.

It is also used for the four branches of Judaism (Orthodox, Conservative, Reform and Reconstructionist), and for the main branches of Islam (Sunnism and Shi'ism, Quranism, Ibadism, Sufism, Muwahhidism).

In Hinduism the major deity or philosophical belief functions as the identifier of a denomination and typically each has distinct cultural and religious practices. The major denominations include Shaivism, Shaktism, Vaishnavism, Smartism, and Halumatha.

The word denomination is used for a large group of Christian people right across the world who use the same name, the same sort of organisation and have the same (or very similar) beliefs.  Christianity is divided into ten main groups. These groups all branched out at different dates from the early Christianity founded by the followers of Jesus. The splits generally happened because they could not agree on certain beliefs or practices. The groups then divided into smaller groups. Each group that has its own separate name is a "denomination". The word "denomination" means "Being given a name”

Denominations
Worldwide Christianity is divided into 10 major groups :
 Catholic
 Eastern Orthodox
 Oriental Orthodox (Miaphysite)
Church of the East (Nestorian)
 Anglican 
Lutheran
Reformed
Anabaptist
Evangelical
Nontrinitarian

Each of these ten has important subdivisions. There are also other (smaller) groups that are not mentioned here.
The Evangelical and Nontrinitarian branches of Christianity are much more divided up than any of the others. Each separate Evangelical church is often called a "denomination". While the Roman Catholic Church looks to a single earthly leader, the Pope, and has similar beliefs right across the world, the several Protestant denominations do not look to a single leader and sometimes have beliefs that are very different from each other. 

Many Christian denomination see themselves as part of the worldwide Church which includes other denominations as well. Some denominations, such as the Roman Catholic and Orthodox Churches and some Protestant Churches, believe that they are the only true Christian church. 

Some denominations have beliefs which almost all the other denominations would disagree with, very strongly. These beliefs are called "heresy" by the other churches.
Numerical comparisons are also problematic. Some groups count membership based on adult believers and baptized children of believers, while others only count adult baptized believers. Others may count membership based on those adult believers who have formally affiliated themselves with the congregation. In addition, there may be political motives of advocates or opponents of a particular group to inflate or deflate membership numbers through propaganda or outright deception.

Protestantism is the second largest major group of Christians by number of followers. Estimates vary from 800 million to a billion, or nearly 40% of all Christians. The main reason for this wide range is the lack of a common agreement among scholars as to which denominations constitute Protestantism. For instance, most sources but not all include Anabaptism, Anglicanism, Baptists and Independent Nondenominational Christianity as part of Protestantism. Moreover, Protestant denominations altogether do not form a single structure comparable to the Catholic Church, or to a lesser extent the Eastern Orthodox Communion. However, several different comparable communions exist within Protestantism, such as the Anglican Communion, World Communion of Reformed Churches, World Baptist Alliance, World Methodist Council and the World Lutheran Federation. Regardless, 900 million is the most accepted figure among various authors and scholars, and thus is used in this article
. Note that this 900 million figure also includes Anglicanism, as well as Anabaptists, Baptists and multiple other groups that might sometimes disavow a common "Protestant" designation, and would rather prefer to be called, simply, "Christian".

The denominations listed below did not emerge from the Protestant Reformation of the 16th century or its commonly acknowledged offshoots. Instead, they are broadly linked to Pentecostalism or similar other independent evangelical and revivalistic movements that originated in the beginning of the 20th century. For this reason, several sources tend to differentiate them from Protestants and classify them as together as Independents, Non-core Protestants etc. Also included in this category are the numerous, yet very similar Nondenominational churches. Nonetheless, sources eventually combine their numbers to the Protestant tally. Despite the absence of centralized control or leadership, if considered as a single cohort, this will easily be the second largest Christian tradition after Roman Catholicism. According to the Center for the Study of Global Christianity (CSGC), there are an estimated 450 million Independents world-wide, as of mid-2019.
