Angle Bisector Theorem - Proof, Converse, Formula, Examples
WEBAngle bisector theorem states that the bisector of any angle will divide the opposite side in the ratio of the sides containing the angle. Learn more about this interesting concept of triangle angle bisector theorem formula, proof, and solved examples.
Angle Bisector Theorem | Brilliant Math & Science Wiki
WEBThe angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
Intro to angle bisector theorem (video) | Khan Academy
WEBThe Angle Bisector Theorem states that when an angle in a triangle is split into two equal angles, it divides the opposite side into two parts. The ratio of these parts will be the same as the ratio of the sides next to the angle. Created by Sal Khan.
