Parallel Lines Cut by a Transversal

This Parallel Lines Cut by a Transversal unit plan also includes:

Use the parallel lines to find your way. After first reviewing geometric constructions and the relationships between angles formed by parallel lines and a transversal, young mathematicians write proofs for theorems relating to parallel lines. They then use their knowledge of parallel lines and constructions to create maps that match given descriptions.
