1 8.5 Proportions in Triangles
Goal: To use the Side-Splitter Theorem

2

3 Theorem: If a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally.

4

5 Corollary: If three parallel lines intersect two transversals, then the segments intercepted on the transversals are proportional.

6

7 Theorem: If a ray bisects an angle of a triangle, then it divides the opposite side into two segments that are proportional to the other two sides of the triangle.
