Find the measures of each exterior angle of a regular Decagon
In a regular decagon, all sides are same size and measure of all interior angles are same. The sum of interior angles of decagon is (n − 2) × 180 o where n is number of sides of polygon. (10 − 2) × 180 o = 1440 o here n = 10 because deca means 10 Each interior angle = 1440 / 10 = 144 o As we know that the sum of interior and exterior ...
