Have you heard of the Triangle Angle Bisector Theorem?

4. DrPepperx3 Group Title

no I haven't :c

5. mathstudent55 Group Title

Here it is. This theorem states that an angle bisector in a triangle divides the opposite side into two segmetns that are proportional to their adjacent sides. |dw:1393541518885:dw|

ohhhh okay ! will you check my work ?

7. DrPepperx3 Group Title

wait but it doesn't give a?

In the figure above, segment AD bisects angle CAB. That means the two segments of the opposite side of angle CAB, CD and BD are proportional to the sides AC and AB, respectiveley, as the proportion shows.

9. mathstudent55 Group Title

Solve the lower proportion by cross multiplying. |dw:1393541799522:dw|
