In geometry, a pentacontagon or pentecontagon or 50-gon is a fifty-sided polygon. The sum of any pentacontagon's interior angles is 8640 degrees.
A "regular pentacontagon" is represented by Schläfli symbol {50} and can be constructed as a quasiregular truncated icosipentagon, t{25}, which alternates two types of edges.
One interior angle in a regular pentacontagon is 172°, meaning that one exterior angle would be 7°.
The area of a regular pentacontagon is (with )
and its inradius is
The circumradius of a regular pentacontagon is
Since 50 = 2 × 5, a regular pentacontagon is not constructible using a compass and straightedge, and is not constructible even if the use of an angle trisector is allowed.
Coxeter states that every zonogon (a 2"m"-gon whose opposite sides are parallel and of equal length) can be dissected into "m"("m"-1)/2 parallelograms.
In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. For the "regular pentacontagon", "m"=25, it can be divided into 300: 12 sets of 25 rhombs. This decomposition is based on a Petrie polygon projection of a 25-cube.
Hexacontagon
A hexacontagon or 60-gon is a shape with 60 sides and 60 corners.
A "regular hexacontagon" is represented by Schläfli symbol {60} and also can be constructed as a truncated triacontagon, t{30}, or a twice-truncated pentadecagon, tt{15}. A truncated hexacontagon, t{60}, is a 120-gon, {120}.
One interior angle in a regular hexacontagon is 174°, meaning that one exterior angle would be 6°.
The area of a regular hexacontagon is (with )
and its inradius is
The circumradius of a regular hexacontagon is
This means that the trigonometric functions of π/60 can be expressed in radicals.
Since 60 = 2 × 3 × 5, a regular hexacontagon is constructible using a compass and straightedge. As a truncated triacontagon, it can be constructed by an edge-bisection of a regular triacontagon.
Coxeter states that every zonogon (a 2"m"-gon whose opposite sides are parallel and of equal length) can be dissected into "m"("m"-1)/2 parallelograms.
In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi. For the "regular hexacontagon", "m"=30, and it can be divided into 435: 15 squares and 14 sets of 30 rhombs. This decomposition is based on a Petrie polygon projection of a 30-cube.
Myrmidons
The Myrmidons (, "Myrmidones") were a legendary people of Greek mythology. Native to the region of Thessaly, they were said to be the fiercest and strongest of all the warriors in Greece; during the Trojan War, they were led by Achilles, as described in Homer's "Iliad". According to Greek myth, they were created by Zeus from a colony of ants, from which their name is derived - Greek "myrmex" (), meaning "ant".

Government of India Act 1858
The Government of India Act 1858 was an Act of the Parliament of the United Kingdom (21 & 22 Vict. c. 106) passed on August 2, 1858. Its provisions called for the liquidation of the British East India Company (who had up to this point been ruling British India under the auspices of Parliament) and the transference of its functions to the British Crown.
The Act ushered in a new period of Indian history, bringing about the end of Company rule in India. The era of the new British Raj would last until Partition of British India in August 1947, at which time all of the territory of the British Raj was granted Dominion status within the Dominion of Pakistan and the Dominion of India.
Government of India Act 1947
The Indian Independence Act 1947 (1947 c. 30 (10 & 11. Geo. 6.)) is an Act of the Parliament of the United Kingdom that partitioned British India into the two new Independent Dominions of India and Pakistan. The Act received the royal assent on 18 July 1947, and Pakistan came into being on 14 August and India came into being on 15 August.
There was much violence, and many Muslims from what would become India fled to Pakistan; and Hindus and Sikhs from what would become Pakistan fled to India. Many people left behind all their possessions and property to avoid the violence and flee to their new country.
