#### 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.
