Geometric Puzzle Foundations

More on measurements of angles of polygons with n sides. .
When n = 3 this is a triangle, n=4, a quadrilateral, or when n= 5, a pentagon.

The sum of the measures of the interior angles of a triangle is 180 degrees.
What about a quadrilateral? and a pentagon?  or an n sided polygon  ( an "n -gon")?
