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.
