Learn the definition, proofs and applications of the angle bisector theorem, which relates the lengths of a triangle's sides and its angle bisectors. See also the exterior angle bisector theorem and its history.
Angle 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.
Learn the angle bisector theorem for triangles, which states that the angle bisector divides the opposite side into two parts proportional to the other two sides. See the proof, converse, and applications with examples and FAQs.
The 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.
