Exterior Angle Bisector


The exterior bisector of an Angle is the Line or Line Segment which cuts it into two equal Angles on the opposite ``side'' as the Angle.


For a Triangle, the exterior angle bisector bisects the Supplementary Angle at a given Vertex. It also divides the opposite side externally in the ratio of adjacent sides.
