WebSince all interior angles in a regular polygon are equal, we can say that the interior angle of polygon = sum of interior angles ÷ number of sides. Now, we know that sum of exterior angles of a regular polygon is 360 °. The formula to calculate the measure of an exterior angle is: exterior angle of polygon = 360 ° ÷ number of sides = 360 ° /n. WebAn Interior Angle is an angle inside a shape. Example: ... Pentagon. A pentagon has 5 sides, and ...
