The angle bisector theorem states that an angle bisector divides the opposite side of a triangle into two segments that are proportional to the triangle's other two sides. So, ∠AOC = ∠BOC which means ∠AOC and ∠BOC are congruent angles. What most textbooks call the Angle Bisector Theorem is this: Angle Bisector Theorem. The three angle bisectors are concurrent. 1. Angle bisector theorem is a theorem in geometry proposed by Euclid, the father of geometry. The angle bisector theorem is totally easy to prove using trig, which is why it isn’t really needed explicitly; you kinda can’t help but derive it from the Law of Sines. C-8 Angle Bisector Conjecture - If a point is on the bisector of an angle, then it is equidistant from the sides of the angle.
Triangle Angle Bisector Theorem. In some textbooks, it refers to the theorem which states that any point on an angle bisector is equidistant from the two sides of the angle. XP = YP for an acute triangle XP = ZP for an acute triangle YP = ZP for an obtuse triangle ZP = XP for a right triangle XP = YP for an obtuse triangle The point of concurrency of the perpendicular bisectors in a triangle is called the circumcenter of the triangle. Triangle Angle Bisector Theorem An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle. C-8 Angle Bisector Conjecture - If a point is on the bisector of an angle, then it is equidistant from the sides of the angle. : p. 149 The angle bisector theorem states that an angle bisector divides the opposite side of a triangle into two segments that are proportional to the triangle's other two sides. In fact, the point where all the angle bisectors intersect is called the incenter of the triangle, and that is why the angle bisector theorem is sometimes called the incenter theorem. The angle bisector is a line that divides an angle into two equal halves, each with the same angle measure. Proving The Angle Bisector Theorem . Click on "Proof of Angle Bisector Thm" to see the ratio in action! If an angle bisector of an angle ∠A in a triangle ABC divides the opposite side in the same ratio as the sides adjacent to the angle, it will be called as Angle Bisector. If a line is parallel to a side of a triangle, and it intersects the other two sides of the triangle, then it divides these sides proportionally (Triangle Proportionality Theorem). Just for fun, I’ll show the proof from Rational Trigonometry. In the triangle ABC, the angle bisector intersects side BC at the point D. This theorem gives the relation between the sides of the triangle and its angle bisector. By the Angle Bisector Theorem, B D D C = A B A C… Okay, we laid the groundwork.

Triangle Angle Bisector Theorem Angle Bisector Theorem Warning: This name is used differently in different textbooks. What most textbooks call the Angle Bisector Theorem is this: An angle bisector in a triangle divides the opposite side into two segments which are in the same proportion as the other two sides of the triangle.

In a triangle, the bisectors of two exterior angles and the bisector of the other interior angle are concurrent (meet at a single point). Angle Bisector Theorem. It has been illustrated in the diagram shown below. Theorem. An angle bisector is a line segment, ray, or line that divides an angle into two congruent adjacent angles. For more details, check our angle bisector theorem. Example of Angle Bisector: Consider an Angle ∠ABC = 90 0. By the Angle Bisector Theorem, B D D C = A B A C Proof: Draw B E ↔ ∥ A D ↔ .
