Triangles A B C and M Q R are shown. The lengths of sides A C and R M are congruent. Angle A C B is 60 degrees and angle R M Q is 64 degrees. Triangle A B C is rotated 90 degrees up and to the left to form triangle M Q R. What additional information could be used to prove ΔABC ≅ ΔMQR using SAS? Select two options. m∠A = 64° and AB = MQ = 31 cm CB = MQ = 29 cm m∠Q = 56° and CB ≅ RQ m∠R = 60° and AB ≅ MQ AB = QR = 31 cm
