1. Have participants draw concave polygons and measure the angles, similar to the previous situation. Drawing the triangles in the concave polygons may be a bit tricky. Have the participants label the triangles as they make them. http://www.mste.uiuc.edu/m2t2/algebra/regs.gsp is a Geometer's Sketchpad file of regular polygons.
