How do i suppose to sequence of rigid motions

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)
