The criteria of congruence used in the figure is SAS ( Side - Angle - Side) Congruence.
The figure shows us that One angle in both triangles are equal .
The angles are alternative interior if taken the common side as transvesal. So, As the angles are equal; Lines are parallel .
We know that distance between parallel lines is equal .So one more side is equal in both triangles.
Also, there is a common side for both of the triangles .
Hence, Both the triangles are congruent
