For interior, the angle sum is 540 degrees, for exterior, the angle sum is 1260 degrees.

Partially correct!

The sum of the exterior angles of any polygon is 360 degrees. The exterior angle is the supplement of the interior angle (180 - interior), NOT the reflex angle (360- interior). So the sum given 1260, which is based on the reflex angles is incorrect.
