Similarity of Angle Bisectors in Triangles
How to solve the similarity of angle bisectors in triangles problems: definition, example, and its solution.
The angle bisector of a triangle is a line segment
that starts from the vertex
and bisects the angle of the vertex.
If two triangles are similar,
then their angle bisectors are proportional.
So the angle bisectors and the sides are proportional:
9 / x = 10 / 7.
