INTERIOR AND EXTERIOR ANGLES OF POLYGONS
WebJun 5, 2024 · So you can find the size of the exterior angles of a regular polygon quite easily: If there are 18 sides (n = 18), then each exterior angle is: 360° n = 360° 18 = 20°. The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line. ∴ each interior angle is 180° − 20° = 160°. Answer link.
