Answer
BA corresponds to QP
AC corresponds to PR
CB corresponds to RQ
Work Step by Step
1.Angles labeled on the diagram correspond, you just need to pair them up as congruent
$\angle B - \angle Q$
$\angle A -\angle P$
$\angle C - \angle R$
2. You just need to look: if both angles on the line correspond, then the lines correspond. Sounds like tautology, but you just need to focus on angles first, then on the sides.
You will get $AB -PQ$ ;$BC- QR$; $CA- RP$ lines corresponding to each other.
