Relationships of Jul 15, 2014 · The proofs for parallel lines and transversals are a little more abstract and involve more vocabulary than congruent triangle proofs so trying to launch from the intro to proofs unit straight into parallel lines and transversals was too big a jump. Theorem If two parallel lines are cut by a transversal, the same side interior angles are supplementary. Theorem If a transversal is perpendicular to one of two parallel lines, it is perpendicular to the other line also. Summarizing, we have: If two parallel lines are cut by a transversal, then the corresponding∠’s are congruent. assign the worksheets on an individual basis, only to those students who need extra help.

Proving Lines are Parallel Students learn the converse of the parallel line postulate. If two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. If two lines are cut by a transversal and alternate interior angles are congruent, then the lines are parallel.

The focus of this lesson is obviously proving theorems involving parallel lines cut by a transversal, but the lesson is also part of a learning progression related to axiomatic systems. The goal in this section of the lesson is to be explicit about what an axiomatic system is and how axiomatic systems operate.
