The sum of the exterior angles of any convex polygon is 360 degrees. That means that if you have n sides, then each exterior angle of a regular polygon is 360/n. If you can find out how the exterior angle is related to the interior angle, you can finish the solution. Stephen La Rocque.> Hi, While it could be done, with algebra, using interior angle sums etc. I would suggest it is easier to understand using exterior angles. The key fact is that the sum of the exterior angles of a convex polygon is 360 degrees  period! Walter
