Polygon Angle Sum Theorems

I introduce Polygon Angle Sum Theorems, not Polynomial Angle Sum Theorem which isn't even a theorem! This includes finding the Sum of the Interior Angles of a Polygon and the Sum of the Exterior Angles. I also talk about finding the individual interior and exterior angles of Regular Polygons...after I define what a Regular Polygon is:) EXAMPLES AT 3:30 4:29 5:38 7:00 10:40 14:18 15:22 17:26 I do not know why I wrote Polynomial Angle Sum Theorem???!!! Too many hours working between teaching and YouTube I guess.
