A Regular Polygon

If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.

(number of sides-2)*180 = sum of interior angles of a polygon

The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.

You can do it by memorizing this statement:" The sum of the exterior angles of every polygon is 360 degrees. "
