In the figure given below, ΔABC≅ΔMBC. The corresponding side to BA is ......
Given △ABC≅△MBC.
Then the corresponding parts will also be equal.
That is by CPCT rule, corresponding parts of congruent triangles are equal.
Then,
AB=MB, BC=BC, AC=MC, ∠A=∠M, ∠B=∠B and ∠C=∠C.
Thus, AB=MB ⟹ BA=BM.
Hence, option A is correct.
