Interior and Exterior angles of Polygons Y8
Interior angles formula for finding the sum of interior angles is 180(n-2). This is used in irregular polygons. formula for finding the size of a interior angle of regular polygons is (180(n-2))/n formula for finding the number of sides for a interior angle is (180-int. angle)/360 Exterior angles Formula for finding the size of an exterior angle: 360/n Formula for finding the number of sides using ext. angle= 360/ext. angle.
