Introduction
Constructions Involving Angles and Parallel Lines

Lines and rectangles drawn on paper

In this topic, you will study constructions involving angles and parallel lines using a compass and a straightedge. During your exploration, you will learn how to construct congruent angles. Congruent angles are angles that have the same measure. Also, you will explore how to construct parallel lines using your new knowledge of constructing congruent angles.
