Use this construction to investigate the sum of the exterior angles of a polygons.
1. Use the slider to resize the quadrilateral. What is the sum of the exterior angles of a quadrilateral?
2. Use the red point on the quadrilateral to change the angle measures. Now use the slider to resize the quadrilateral. Does changing the angle measures effect the sum of the exterior angles?
