If it's regular then 360/20 = 18 degrees
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.
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
If it's regular then 360/20 = 18 degrees
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
