Chapter 3: Parallel and Perpendicular Lines

3.1: Pairs of Lines and Angles

EQ: Are parallel lines the only ones that don’t intersect?

Core Concept boxes (p. 126 and 129) are the most important ideas to know. Know the difference between parallel and skew lines. You also need to know the 4 pairs of angles formed when any 2 lines (not necessarily parallel — that’s the next lesson) are crossed by a transversal. Look at examples 1 and 3 (the ones after the Core Concept boxes).

Prep work: p129(3-31)
