Answer:
the second option: QPR~STR, ASA
Step-by-step explanation:
This would be congruent by ASA. this is because it's given that ∠Q and ∠S are similar, which would be the first "A". then, it's given that QR = SR, which is the "S" or side. The final "A" would be the vertical angle properties of ∠SRT and ∠QRP
The order of the triangles in the final answer needs to be the same, so the second option
