A polygon is a closed plane figure that is bounded by straight sides. There may be three or more sides - up to any number. The sides can be the same size or different. It must have the same number of sides as vertices. The angles may be the same or different. The sum of the exterior angles is 2*pi radians. The sum of the interior angles of a polygon with n sides is (n-2)*pi radians.

1 radian = 180 degrees.
