The size of each exterior angle of a regular polygon is 40 degrees.

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

 

Because the number of sides in a polygon is equal to the number of exterior angles, I can say that the number of exterior angles is x, which also means that there are x sides. 

 

40x = 360

 

x = 9

 

This is a nine sided regular polygon!

 

I hope this helped,
