What is 20 sided shape?

A 20-sided shape is called an icosagon. It is a polygon that has 20 sides, 20 angles, and 20 vertices. Each angle in an icosagon measures 162 degrees.

The interior angles of an icosagon add up to a total of 3240 degrees. The exterior angles of an icosagon add up to 360 degrees.

Icosagons can be regular or irregular, with regular icosagons having all sides and angles equal in size. Regular icosagons have a symmetry of order 20, meaning they can be rotated by a certain angle and still look the same.

Icosagons are used in various geometric applications and can be found in art, architecture, and design.
