Understanding Interior and Exterior Angles in Triangles An exterior angle is formed when one of the sides is extended. This creates two angles that are equal to 180 degrees, the adjacent interior and new exterior angle. The goal of this second lesson is to show students that the sum of the two remaining interior angles (opposite the exterior angle) are equal to the exterior angle.
