Step 1:Calculate the size of the exterior angles of a polygon by subtracting the size of the interior angle from 180.

Step 2:Divide 360 by the size of a single exterior angle.

EXAMPLE:

The interior angles of a regular polygon are each 140 degrees. How many sides does the polygon have?

Step 1:Calculate the size of a single exterior angle by subtracting the size of the interior angle from 180.

180 – 140 = 40

Step 2:Divide 360 by the size of a single exterior angle.

The polygon has nine sides. It’s a nonagon!
