Angle Sums
Curator: Kirk Sheren
This applet allows the student to explore the sum of angles property for different polygons. Students can choose a polygon from a triangle to an octagon, and are then able to drag vertices, changing the shape of the polygon. The applet automatically changes each angle measurement as well as updates the sum of the angles. Students should be able to see that as the angles change in the polygon, the sum of the angles remains the same.
