Exterior Angles
... Recall that interior means inside and that exterior means outside. So, an exterior angle is an angle on the outside of a polygon. An exterior angle is formed by extending a side of the polygon. ...

... measure of an obtuse angle is greater than 90°, and if there were four or more exterior angles that each measured more than 90°, their sum would be greater than 360°. That is impossible because the sum of all the exterior angles (one at each vertex) is 360° for any polygon. The minimum number of acu ...
