Answer:
ASA
Step-by-step explanation:
The angles shown to be congruent are on either end of the side shown to be congruent. That is, in order, you have a corresponding Angle, a corresponding Side, and a corresponding Angle that you have shown to be congruent. Hence you can claim triangle congruence by the ASA theorem.
_____
Angles U and Q are at either end of segment QU, so the segment is between the angles. If it were off to one side of the two angles, then you would claim AAS congruence.
