Since there would be no diagonal drawn back to itself, and the diagonals to each adjacent vertex would lie on top of the adjacent sides,. X = interior angle y = exterior angle a = area p = perimeter π = pi = 3.1415926535898 √ = square root calculator use polygon calculator. Hence, we can say, if a polygon is convex, then the sum of the degree measures of the exterior angles, one at each vertex, is 360°.

An interior angle is an angle inside a shape. The radius of a regular polygon is the distance from the center to any vertex.it will be the same for any vertex. The angle next to an interior angle, formed by extending the side of the polygon, is the exterior angle. Make sure each triangle here adds up to 180°, and check that the pentagon's interior angles.
