it is called icosikaiheptagon
A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
An 11 sided polygon is a hendecagon and a 12 sided polygon is a dodecagon
icosihenagon= 21-sided polygon icosihenagon= 21-sided polygon
Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
The name of a 12 sided polygon is Dodecagon.
27-agon
A 27-sided shape is called a heptacosagon. The prefix "hepta-" denotes the number 7, and the suffix "-gon" signifies a polygon with that many sides. Therefore, a 27-sided polygon is specifically referred to as a heptacosagon in geometry.
The names of polygons with sides ranging from 21 to 30 are as follows: a 21-sided polygon is called a icosagon, a 22-sided polygon is a dicosagon, a 23-sided polygon is a tricosagon, a 24-sided polygon is a tetracosagon, a 25-sided polygon is a pentacosagon, a 26-sided polygon is a hexacosagon, a 27-sided polygon is a heptacosagon, a 28-sided polygon is an octacosagon, a 29-sided polygon is a nonacosagon, and a 30-sided polygon is a triacontagon.
Well honey, a 27-sided polygon has 27 interior angles. To find the sum of those angles, you use the formula (n-2) * 180, where n is the number of sides. So, for a 27-sided polygon, you'd have (27-2) * 180 = 4,860 degrees. Math doesn't lie, darling.
The sum of the exterior angles of any polygon, including a 27 sided one, is 360 degrees.

A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
To find the interior angle of a polygon, you can use the formula: interior angle = (n-2) * 180 / n, where n is the number of sides of the polygon. In this case, for a 27-sided shape, the interior angle would be (27-2) * 180 / 27 = 150 degrees.
An 11 sided polygon is a hendecagon and a 12 sided polygon is a dodecagon
