Proving Lines Parallel

Show it can all be proved. Scholars learn the converses of the properties of parallel lines. Using the converses, pupils determine which lines are parallel based on angle measurements and practice using a flow proof to show that two lines are parallel based on given information. At the end, individuals practice their skills about parallel lines along with a review of applying constructions to solve problems.
