Figuring out lengths of triangle
WebEach triangle has a sum of 180°. Thus, the sum of the angles of any polygon is: S = ( n – 2) * 180. For example, the sum of all eight angles of an octagon is: S = (8 – 2) * 180 = 1080°. This formula works whether or not the polygon is regular and even works if the polygon is convex. The Red Cross symbol is a convex 12-gon.
