In this question, the triangles are congruence which means that the two triangles will have same side and angle. The corresponding part can be seen from how the triangle is written. In this case, the triangle seems to be reflected with vertical lines. Using the picture it would be:
PQ= TS
QR=SR
RP=RT
Since your written answer is not same with the picture, then the written answer version would be:
PA=HE
AR=ER
RP=RH
