Warm Up Week 6

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

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

Ex 1

Ex 2

Line proportionality If three Parallel lines intersect two transversals, then they divide the transversal proportionally. Theorem 8.6
