Using the polygon exterior angle set
Students measure the exterior angle on each polygon, 120, 90, 72 and 60 degrees for the triangle, square, pentagon and hexagon, and compare the values, discovering that each equals 360 degrees divided by the number of sides and that the exterior angles always total 360 degrees.
