Webb[Hint: To prove the above theorem, we will be using the following axioms: Corresponding Angle Axiom: When two lines are parallel the corresponding angles are congruent angles. The converse of Corresponding Angle Axiom: When the corresponding angles made by two lines are congruent, then those two lines are parallel.] To Prove: ∠1 = ∠7. Proof: Webbthat as long as we have one pair of alternate interior angle congruent, the lines will be parallel, so the two line will be parallel if we could prove \4 ˘=\6, or \3 ˘=\5. The converse of the theorem says that, when two lines are parallel, then all corresponding angles are congruent, so given that ABjjCD, then \4 ˘=\6, and \3 ˘=\5. how do i reenter my fingerprint
