standard_description: Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions.
problem_activity: A rotation of 180° about the origin and reflections about two axis are equivalent transformations.
Describe two other sets of equivalent transformations. Provide a diagram to support your reasoning.
