In two triangles; if a pair of corresponding angles and a side are equal, then the triangles are necessarily congruent.
True
In two triangles,
If a pair of corresponding angles and the included side are equal, then they are congruent [ASA congruence criterion].
If a pair of corresponding angles and a non-included side are equal, then they are congruent [AAS congruence criterion].
Therefore, given statement is true.
