Triangle PQR undergoes a series of rigid transformations and forms triangle STU. using only the give and no other calculations, which criteria can be used to prove triangle PQR is congruent to triangle STU

We have two triangles that have two pair of congruent angles and one pair of congruent sides.
This correspond to the ASA (angle-side-angle) postulate, as the congruent side is between the two congruent angles.
Answer: Angle-side-angle congruence theorem.
