Sum of interior angles of a polygon main concept an interior angle is an angle located inside a shape for example, a triangle has three interior angles, with a. Any of the four angles formed on the inside of two straight lines when crossed by a transversal the angle formed inside a polygon by two adjacent sides. To adapt, as needed, at least one commonly-used method for calculating the sum of a polygon's interior angles, so that it can be applied to convex and concave. Since an interior angle is 150 degrees, its adjacent exterior angle is 30 degrees exterior angles of any polygon always add up to 360 degrees.
