In this session, we will examine why we study transformational geometry and how to use translations, reflections, and rotations in the plane to develop a precise definition of congruence. Basic rigid motions are embedded in Eureka/EngageNY (grade 8). Investigative activities will be used to clarify the meaning of congruence and to review the foundational and practice standards and other topics.
