The sum of the interior angles of an icosagon is 3240 degrees, each angle of a regular icosagon being 162 degrees.
* The formula for the sum of an n-sided polygon is 180 (n-2). 180 x 18 = 3240
If it's regular then 360/20 = 18 degrees
Shapes with 12 to 20 sides are named as follows: a 12-sided shape is called a dodecagon, a 13-sided shape is a triskaidecagon, a 14-sided shape is a tetradecagon, a 15-sided shape is a pentadecagon, a 16-sided shape is a hexadecagon, a 17-sided shape is a heptadecagon, an 18-sided shape is an octadecagon, a 19-sided shape is a nonadecagon, and a 20-sided shape is an icosagon.
A 20-sided polyhedron is an icosahedron. A 20-sided polygon is an icosagon.
Icosahedron is a 20 sided polygon.
Any of these shapes is practically circular. A 20-sided shape is an icosagon. a 50-sided shape is a pentacontagon (aka pentecontagon). A 100-sided shape is a hectogon (aka hecatontagon). A 1000-sided shape is a chiliagon.
