Answer 3

>> by algebra only

@CrashOnce By "algebra only," you are speaking of a coordinate geometry proof, correct?

Answer 4

co-ord geo is fine

Answer 5

@Directrix do you have a method

Answer 6

I'm not sure. What I need to know is if by Angle Bisector Theorem, you mean the Triangle Angle Bisector Theorem?

@CrashOnce What is the statement of the theorem you need to prove?

Answer 7

I just have to prove the angle bisector theorem using only algebra
