Determining and using triangle congruence 

Learning Targets:
✳ I can use and describe rigid motions to decide if two figures are congruent (MGSE9-12.G.CO.6)
✳ I can use the definition of congruence to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent. (MGSE9-12.G.CO.7)
✳ I can explain how the criteria for triangle congruence (SSS, SAS, ASA, AAS, and HL) follow from the definition of congruence in terms of rigid motions. (MGSE9-12.G.CO.8)
