Answers to additional practice: 1. a. angle; T, STQ, QTS. When lines are parallel, they will never intersect (touch/cross) because they have the same slope, and are therefore always the same distance apart (equidistant). Similarly, the other theorems about angles formed when parallel lines are cut by a transversal have true converses. 11. Explain your answer.
