In geometry, an equilateral triangle is a triangle where all three sides are the same length and all three angles are also the same and are each 60°. If an altitude is drawn, it bisects the side to which it is drawn, in turn leaving two separate 30-60-90 triangles Principal properties. Denoting the common length of the sides of the equilateral triangle as "a", we can determine using the Pythagorean theorem that: Denoting the radius of the circumscribed circle as "R", we can determine using trigonometry that: Many of these quantities have simple relationships to the altitude ("h") of each vertex from the opposite side: In an equilateral triangle, the altitudes, the angle bisectors, the perpendicular bisectors and the medians to each side coincide. Equal cevians. Three kinds of cevians are equal for (and only for) equilateral triangles: Coincident triangle centers. Every triangle center of an equilateral triangle coincides with its centroid, which implies that the equilateral triangle is the only triangle with no Euler line connecting some of the centers. For some pairs of triangle centers, the fact that they coincide is enough to ensure that the triangle is equilateral. In particular: Six triangles formed by partitioning by the medians. For any triangle, the three medians partition the triangle into six smaller triangles. formula_12

Fir Park is a football stadium in Motherwell, North Lanarkshire, Scotland. The stadium is the home of Scottish Premier League club Motherwell F.C.. The stadium is all seats with a capacity of 13,742. The highest attendance for the stadium is 35,632 against Rangers in a 1952 Scottish Cup match. Today, the stadium has an unbalanced look, with one large stand and three smaller stands. The biggest stand at the ground is the two-tiered "South Stand", which was built in 1993. Opposite is the small "Davie Cooper Stand", named after the former player, which was built in 1995. These two stands have their advertising slogans changed whenever the club's sponsor changes. Running along one side of the ground is the "East Stand", which used to be a terrace until it was changed into a seating area. This stand had the legendary "KEEP CIGARETTES AWAY FROM THE MATCH" slogan displayed below the roof, facing the pitch. Since the smoking ban was put into place in 2006, slogans such as these were no longer needed, and in 2012, was changed to Cash Converters, the clubs main sponsor. The East stand is the stand of choice for many of the younger and passionate fans of the club. Opposite the "East Stand" is "The Phil O'Donnell Stand", which was known as the "Main Stand" until 2008. The stand was renamed "The Phil O'Donnell Stand" in honour of the late Motherwell captain who died on the Fir Park pitch. This is a strange-looking stand, as the steel girders run for the full length of the pitch, but the stand only runs for two thirds the length of the pitch. This was because, in 1962, a nearby houseowner complained about the building of the stand during construction. Both the club and the houseowner failed to work things out, so to this day, the stand has not been built the full length of the pitch. Gretna. During the 2007-08 season, Gretna F.C. rented Fir Park from Motherwell and played all but one of their home league games there.

In India, people fly kites on Makar Sankranti. History. Kites come in all shapes and sizes. Kites were created in China about 2,800 years ago. Later they spread into other Asian countries, like (India), Japan and Korea. However, the kite only appeared in Europe around the year 1600 The first kites had sails made of paper or light fabrics such as silk. The poles were made from bamboo sticks, or other strong but flexible woods. The kite line was made from string, or twine. Modern kites are made from synthetic materials, such as ripstop nylon or more exotic fabrics on the sails. They have fiberglass or carbon fiber poles, and use dacron or dyneema for the kite lines.  Today, there are different types of kites. Some are large and are made to look good. Some are smaller and are made for speed, children and competitions. Also, there are many different types of kites. The most important types of kite are stunt kites and parafoil kites. However, they can come in a variety of sizes, types and designs. Inflatable kites are made in an inflatable shape, animal or other design. The inflatable kite is one the few modern inventions in the world of kite design.  Though the exact origin of kites are not known, it is known that they were flown in China and the Malay Archipelago two to three thousand years ago. The earliest written accounts of kite flying were the exploits of the Chinese general Han Hsin, Han Dynasty (206 B.C.-220 A.D.).

Built between 1079 and 1532, Winchester Cathedral has had an unusual architectural history. The exterior, apart from the modified windows, gives the impression of a massive Norman building and indeed, when first completed, the Norman Cathedral was second only in size to Saint Peter's Basilica in Rome. However, the west front is now Perpendicular, with its huge window filled with fragments of medieval glass. Sadly this glass window was destroyed by the Roundheads.They also messed up the bones of some of the most important rulers. Inside, only the crypt and the transepts have retained their Norman appearance. The spectacular Perpendicular nave with its tall arcade arches and strong vertical emphasis has been literally carved out of the original Norman interior. The Very Rev. Norman Sykes wrote of it “Well might the visitor who enters … by the west door gasp with amazement". Winchester is also famous for its carved wooden fittings of many different periods. Events.

To sponsor something is to support an event, activity, person, or organization. The support can be with money or giving something else useful, such as advertising, or time. A sponsor is the individual or group that gives the support, similar to a benefactor. A sponsor may also be a personal sponsor, a political sponsor or a state sponsor. There are many different kinds of sponsors. Commercial sponsor. A sponsor is one (usually a company) who gives cash, goods or services in return for promoting the sponsor's company. There is a distinct difference between sponsorship and philanthropy. A sponsor expects a return on investment (ROI), usually in the form of advertising. A philanthropist donates something as a charitable contribution. In sports, sponsors compete to advertise in the most popular sports. In India, sponsors all want to be associated with Cricket. It is much harder to find sponsors for other sports. Legislative sponsor. A sponsor or patron, usually a legislator, is someone who presents a bill or resolution for consideration. Others who join the sponsor are known as cosponsors or copatrons. In the United States Congress a sponsor is the first person listed among the lawmakers who introduce a bill to either the Senate or the House of Representatives. The process is very similar to sponsoring a bill in Parliament. Personal sponsor. This is someone who agrees to help another person or persons, and be responsible for them. For example, an employer may sponsor a foreign national to become a permanent resident of the United States by guaranteeing that person a job. Sponsorship can also mean an individual who helps an organization. Many charitable organizations offer personal sponsorship of a boy or girl to help them. Many public radio and television stations ask for sponsors to provide funds for them to operate. At a Ceremonial ship launching the person breaking the champagne bottle over the ship's bow is called the sponsor of that ship. In many religions, godparents are the baptized child's sponsors. State sponsorship. Sponsorship is not always for the purposes of doing good. A state (or government) may sponsor terrorism for their own purposes. While not engaging in activities against another country (or countries) themselves, they may sponsor other groups to do it for them. The United States currently lists four countries who sponsor terrorism. They are: Cuba, Iran, Sudan, and Syria. State sponsors may also be called affiliates and/or supporters.
