1 Warm Up 02.06.12 Week 6

2 Section 8.6 Day 1 I will use proportionality theorems to calculate segment lengths. Triangle Proportionality If a line parallel to one side intersects the other two sides, then it divides the two sides proportionally. Theorem 8.4

3 Triangle Proportionality Converse If a line divides two sides proportionally then it is parallel to the third side. Theorem 8.5
