It is a regular 20 sided polygon
If the 20-sided polygon is a regular polygon, then:The sum of all 20 angles = (20 - 2)180⁰ = 18(180⁰) = 3240⁰Each angle measure = 3240⁰/20 = 162⁰
The interior angles of an x-sided polygon would be: (x - 2) * 180. (20 - 2) * 180 = 3,240
360/20 = 18 degrees.
Regular 20 sided solid is an icosahedron, so a plane equivalent is presumably an icosagon?

Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
360/20 = 18 degrees.
A 20-sided polygon is an icosagon.(see related link)
