Unit 2: Congruence and Similarity
Overview
In this unit you will investigate the effect of transformations on two-dimensional figures. You will then use transformations to explore relationships between angles formed when parallel lines are cut by a transversal and among angles in a triangle. Throughout the unit, you will perform translations, reflections, rotations, and dilations and learn about congruency and similarity. You will deepen your knowledge of geometry and see connections between geometry and algebra. Developed By: Cynthia Burke and Sheila Ruddle
