-recognize when segments are divided proportionally
-recognize and apply the following theorems:
1. If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
2. If 3 parallel lines intersect 2 transversals, then they divide the transversals proportionally.
3. If a ray bisects an angle of a triangle, then it divides the opposite side into segments proportional to the other two sides.
