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 ... WebJun 15, 2024 · The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. Isosceles Triangle Theorem: The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.

WebIncenter. The point of intersection of angle bisectors of the 3 angles of triangle ABC is the incenter (denoted by I). The incircle (whose center is I) touches each side of the triangle. In geometry, the incenter of a triangle is a triangle center, a point defined for any triangle in a way that is independent of the triangle's placement or scale.
