Right angle bisector theorem
WebAug 1, 2024 · The angle bisector theorem states that an angle bisector of a triangle divides the opposite side of the given triangle into two parts such that they are proportional to the other two sides of the provided triangle. Angles in geometry are created when two lines intersect each other at a particular point. An angle is represented by the symbol ∠.
