Triangle Sum Theorem

This applet is designed to help students prove the Angle Sum Theorem. During this assignment, you should move the points around and see if it is possible to create a triangle where the sum of the angles is a number other than 180 degrees. Try at least 5 different triangles. In addition, I expect you to create one isosceles triangle, one equilateral triangle, and one scalar triangle. Compare the different angles and the commonalities/differences in each triangle's angles.
