In a set of congruent triangles, the first angles always correspond, and so do the second and third: ∆ABC and ∆DEF --> ∠A and ∠D correspond, ∠B and ∠E, etc.
This means that the sides also correspond: AB and DE, BC and EF, etc.
Following that logic:
a. ∠Y --> ∠Q (Both are the second angles)
b. ∠X --> ∠P (Both are the first angles)
c. YZ --> QR (Opposite sides of ∠X and ∠P)
d. XZ --> PR (Opposite sides of ∠Y and ∠Q)
e. ∆ZXY --> ∆RPQ (clockwise, ∠R and ∠Z first)
