What is the sum of the exterior angles of any polygon?

Back

The sum of the exterior angles of any polygon is always 360 degrees.

Front

How do you find the number of sides of a polygon given an exterior angle?

Back

To find the number of sides, divide 360 degrees by the measure of one exterior angle.
