Web2 THE EXTERIOR ANGLE IS EQUAL TO THE SUM OF TWO INTERIOR OPPOSITE ANGLE exterior angle is, the supplementary to that angle (linear pair of angles) this means.....imagine a triangle abc the exterior … WebSolution: We know that the sum of exterior angles of a polygon is 360 degrees. Thus, 70° + 60° + 65° + 40° + x = 360° 235° + x = 360° X = 360° – 235° = 125° Example 2: Identify the type of regular polygon whose exterior angle measures 120 degrees. Solution: Since the polygon is regular, the measure of all the interior angles is the same.
