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 ... WebJan 1, 2024 · For an alternative proof using simple geometry, consider the excircle of A B C opposite A and the point E where it touches a, as well as the point F on the incircle opposite to D. Clearly scaling M ′ I N around D by factor 2 yields A F E, and A F E are collinear as seen by the scaling around A mapping the incircle to the excircle.
