Prove triangle angle bisector theorem
WebbAngle Bisector Theorem. of the angle. sides of the angle, then it lies on the bisector of the angle. The points along ray AD are equidistant from either side of the angle. Together, they form a line that is the angle bisector. which the angle bisectors of a triangle meet. WebbThe angle bisector theorem is TRUE for all triangles In the above case, line AD is the angle bisector of angle BAC. If so, the "angle bisector theorem" states that DC/AC = DB/AB If the triangle ABC is isosceles such that AC = AB then DC/AC = DB/AB when DB = DC.
