The Polygon-Angle Sum Theorems

How Do You Find the Angle Measures of a Regular Polygon?

You can use what you already know to find out the angle measures of regular polygons! Watch this tutorial to find out how.
How Do You Find the Sum of the Interior Angles of a Polygon?

Polygons have all kinds of neat properties! For example, if you know the number of sides of a polygon, you can figure out the sum of the interior angles. That knowledge can be very useful when you're solving for a missing interior angle measurement. Check out this tutorial to learn how to find the sum of the interior angles of a polygon!
