Sum of Interior Angles of a Polygon

The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees.

Problem

Prove that the sum of the interior angles of a polygon with n sides is (n-2)*180 degrees.

Solution

by elrichendelgart 
The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees. This is because each interior angle is 180-360/n degrees. When you sum all of the interior angles, you get (n-2)*180 degrees.
