Triangle Angle Theorems (V3)

This resource has been marked as outstanding by a GeoGebra moderator.

Applet powerfully illustrates to the student that the sum of the measures of the interior angles of any triangle is 180 degrees, and that the sum of the measures of the exterior angles of any triangle is 360 degrees. ("Proof" without words.)
