The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
An exterior angle for a polygon is formed by extending one side of the polygon from one if its endpoints. From this, we see that an exterior angle and interior angle form a linear pair of angles. If you extend each side of a polygon to form one exterior angle at each vertex, you get a set of exterior angles. This conjecture tells us that the sum of a set of exterior angles is 360 degrees. This result, all by itself is not so exciting. The resulting corollaries about regular polygons are much more interesting. For example, the first corollary gives a formula for finding the measure of an exterior angle to a regular n-gon.
