About Geometry Worksheet Assignment 6.4:
Assignment 6.4 is an introduction to proportion theorems resulting from pairs of transversals intersecting three or more parallel lines.
Prerequisite Skills: Calculate cross-products (Assignment 6.2). Solve proportions (Assignment 6.2).
Theorems: Parallel lines intercept segments with proportional lengths on all transversals,
Lines that divide common transversals into segments with proportional lengths are parallel.
