In this unit, students learn about transformations such as reflection, rotation, and translation. They understand what determines each type of transformation and use terms like "corresponding sides" and "corresponding angles." They recognize that lengths and angle measures are preserved under these transformations. Students draw figures under rigid transformations and use them to generate shapes and analyze measurements. They also learn about congruence of plane figures and determine whether figures are congruent or not. They investigate angle relationships, including complementary, supplementary, and vertical angles.
