Exterior Angles The well known result that the measure of an exterior angle of a triangle is the sum of the measures of the opposite interior angles, requires the use of the parallel postulate. However, Euclid proved a weaker result (Prop. For the sum of the exterior angles, it is 360° for all polygons. Triangles, quadrilaterals, and pentagons all have exterior angles that sum to 360°. Why do all polygons have exterior angles that sum to 360°? Let’s think about the reason. In order to prove this reason, we need to create a formula for the sum of the interior angles of a polygon.
