What is the interior and exterior angle of a regular hexagon?

Imagine the angle you want to find is part of a circle - 360 degrees. Since a hexagon has 6 sides, you have to divide 360 by 6. This gives you 60. 60 degrees is the size of the exterior angle.

You should know that a straight line is 180 degrees. So all you have to do is take away 60 from 180, giving you an answer of 120 degrees. This is the size of your interior angle.
