Interior Angle And Exterior Angles Of A Polygon. Exterior angles are measures from the adjacent side to an EXTENDED external line from the polygon. The interior and exterior angles together lie on a straight line.
Check out this tutorial and see how to use this knowledge to find those missing measurements. θ 180 β and β 180 θ. In the figure angles 1 2 3 4 and 5 are the exterior angles of the polygon.
As the number of sides in a regular polygon increases so does the size of the interior angles.
