Angle Bisector Definition Examples Cuemath In a triangle, ae is the bisector of the exterior ∠cad that meets bc at e. if the value of ab = 10 cm, ac = 6 cm and bc = 12 cm, find the value of ce. solution: given : ab = 10 cm, ac = 6 cm and bc = 12 cm. let ce is equal to x. by exterior angle bisector theorem, we know that, be ce = ab ac. The angle bisector theorem states that the ratio of the length of the line segment bd to the length of segment cd is equal to the ratio of the length of side ab to the length of side ac: and conversely, if a point d on the side bc of abc divides bc in the same ratio as the sides ab and ac, then ad is the angle bisector of angle ∠ a. The converse of angle bisector theorem states that if the sides of a triangle satisfy the following condition "if a line drawn from a vertex of a triangle divides the opposite side into two parts such that they are proportional to the other two sides of the triangle", it implies that the point on the opposite side of that angle lies on its angle bisector. 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. to bisect an angle means to cut it into two equal parts or angles. say that we wanted to bisect a 50 degree angle, then we.
