WebJun 22, 2024 · You can find the exterior angle measure of a polygon by taking 360 degrees and divide this by the number of sides of the regular polygon.The interior and ext... WebTo find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n. What is the measure of one of the interior angles of a regular polygon if the measure of each exterior angle is 20? Each exterior angle of a regular polygon = 20 deg. So the polygon has 360/20 = 18 sides.
