Chapter 3

Parallel & Perpendicular Lines

In this chapter we will explore line relationships such as parallel, perpendicular, skew, coplanar, intersecting and angle-pair relationships such as corresponding, alternate interior, alternate exterior, and consecutive interior. Throughout this chapter we will not lose sight of the bigger picture with regard to writing proofs. The goal is to write a logical argument based on known information and information that can be deduced from given information. Students will add to the axiomatic system a growing list of theorems, postulates, definitions, and properties. In this chapter the list will grow and students will continue to develop their deductive skills.
