In ΔABC and Δ DEF. AB = DE and BC = EF. Then one can infer that Δ ABC ≅ Δ DEF, when
AB = DE and BC = EF
Two triangles are congruent if two sides and included angle of one are equal to the corresponding sides and the included angle of the other triangle.(SAS criterion)
Thus, if $$\angle$$ABC = $$\angle$$DEF
Then, $$\triangle ABC \cong \triangle DEF$$
