Make sense of problems and persevere in solving them. Objective: I can statement: Use the definition of congruence in terms of rigid I can use the definition of motions to show that two triangles are congruent congruence in terms of rigid if and only if corresponding pairs of sides and motions to show that two corresponding pairs of angles are congruent. triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent. Procedures: Materials: 1. Students will complete the bellringer. Bellringer 53 2. Students will work in groups of at least 5.
