What is an exterior angle of a polygon?

Back

An exterior angle is formed by one side of a polygon and the extension of an adjacent side. The sum of the exterior angles of any polygon is always 360°.

Front

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

Back

To find the number of sides (n) of a regular polygon, use the formula n = 360° / exterior angle.

Front

What is the formula to find the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon with n sides is given by the formula (n - 2) × 180°.

Front

What shape has 4 sides and two sets of parallel sides?

Back
