Exterior Angles of Polygons--Proofs without Words

This applet allows for students to easily see (i.e. "proof without words") that the sum of the measures of the exterior angles of a convex polygon is 360 degrees. This applet allows for students to discover this theorem within the triangle, quadrilateral, pentagon, hexagon, heptagon, and octagon.
