To determine the correct congruence statement based on the given information, we can use the Angle-Side-Angle (ASA) congruence criterion or the Side-Angle-Side (SAS) criterion.

We have the following congruencies:

  • ∠X ≅ ∠L
  • ∠P ≅ ∠M
  • ∠A ≅ ∠K
  • PA ≅ MK
  • AX ≅ KL
  • XP ≅ LM

From these congruences, we can observe that:

  • The angles ∠X and ∠L correspond to vertices X and K.
  • The angles ∠P and ∠M correspond to vertices P and M.
  • The angles ∠A and ∠K correspond to vertices A and K.

Using the information available, we can match the triangles by their corresponding angles and sides:

  1. In the triangle △XPA:

    • ∠X ≅ ∠L
    • ∠P ≅ ∠M
    • Side PA ≅ Side MK
  2. In the triangle △MKL:

    • ∠K ≅ ∠A
    • Side KL ≅ Side AX

Looking at the congruence statements provided:

  • a. △XPA ≅ △MKL
  • b. △PAX ≅ △MKL
  • c. △PAX ≅ △KLM
  • d. △XPA ≅ △KLM

We can conclude that the correct congruence statement based on the information provided is:

a. △XPA ≅ △MKL

This is because all corresponding angles and sides match according to the criteria for triangle congruence.
