Since an exterior angle is formed by extending a side the sum of the interior and the exterior angle on the same vertex of any polygon is 180. How to calculate an angle in a regular polygon is quite simple. Take a look at the graphic below to see how its done. By considering angle sums work out interior and exterior angles of polygons.
