An angle bisector divides the angle into two angles with equal measures. An angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle. The interior or internal bisector of an angle is the line, half-line, or line segment that divides an angle of less than 180° into two equal angles. The exterior or external bisector is the line that divides the supplementary angle (of 180° minus the original angle), formed by one side forming t… WebThe 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. Conclusion: If ABC is an isosceles triangle (also equilateral triangle) D is the ...
