Angles and Parallel Lines COURSE 3 LESSON 8-2 Angles and Parallel Lines In the diagram below, m 5 = 80º, m 6 = 80º, and m 7 = 80º. Explain why p and q are parallel and why s and t are parallel. p || q because 5 and 7 are congruent alternate interior angles. s || t because 6 and 7 are congruent corresponding angles. 8-2

Angles and Parallel Lines COURSE 3 LESSON 8-2 Use the diagram to answer the questions. 1. Classify 4 and 7 as 2. Classify 2 and 8 as alternate interior angles, alternate interior angles, corresponding angles, corresponding angles, or neither. or neither. 3. If a || b and m 8 = 80°, 4. Suppose m 5 = 100° and find m 4. m 3 = 100°. What can you conclude about line a and line b? neither alternate interior angles 80° a || b 8-2
