Side-Splitter TheoremIf lines are || to one side of a triangle and intersects of the two sides, it divides then those side even.
Corollary To Theorem
If there is 3 lines are || that intersect two transversals, then the segments intercepted on the transversals are proportional
Is a ray bisects of a angle of a triangle , then it divides the opposite side into two segments which are even to the other two side of the triangle.
Using 1st theorem Side-Splitter
Solving for x.
Using 3rd theorem Triangle- Angle-Bisector
Finding the value of x.
