## Theorem 6.7- If a ray bisects an angle of a triangle, then it divides the opposite side into segments whose lengths are proportional to the lengths of the other two sides.

AD=4

CA=8

BD=4

CB=8

CA=8

BD=4

CB=8

<BAC is 70 degrees

let's say the point where the bisector meets segment BC is point D

BD is 3. DC is 4 AB is 6 what is the length of AC?

3/6=4/x 1/2=4/x x=8
