What Do Interior And Exterior Angles Add Up To. A Polygon is any flat shape with straight sides. This is true for both regular and irregular heptagons.
They are Supplementary Angles. When we add up the Interior Angle and Exterior Angle we get a straight line 180. A theorem is a proven statement or an.

Quadrilaterals such as a square or parallelogram which has four sides angles add up to. As we know if we add up the interior and exterior angles of one corner of a triangle we always get 180 0. Moreover the sum of three interior angles of a triangle is 180o and the sum of interior angles on a line is also 180o.
