    In triangle ABC, AB = 3 m, BC = 4 m, and  AC = 5 m. In triangle PRQ, PR = 4 m, PQ = 5 m, and RQ = 3 m. Which of the following is a correct order
    Question

    In triangle ABC, AB = 3 m, BC = 4 m, and  AC = 5 m. In triangle PRQ, PR = 4 m, PQ = 5 m, and RQ = 3 m. Which of the following is a correct order of congruency?

    A.

    △BAC congruent to ΔRPQ

    B.

    ΔCBA congruent to ΔRPQ

    C.

    ΔABC congruent to ΔRPQ

    D.

    ΔBCA congruent to ΔRPQ

    Correct option is D

    Given: 

    Triangle ABC:
    AB=3m,BC=4m,AC=5mAB = 3 \, \text{m}, BC = 4 \, \text{m}, AC = 5 \, \text{m}AB=3m,BC=4m,AC=5m

    Triangle PRQ:
    PR=4m,PQ=5m,RQ=3mPR = 4 \, \text{m}, PQ = 5 \, \text{m}, RQ = 3 \, \text{m}PR=4m,PQ=5m,RQ=3m   

    Concept Used: 

    SSS Congruence Criterion:

    Two triangles are congruent if their corresponding side lengths are equal.

    Solution:

    Matching the side:

    AB=3mAB = 3 \, \text{m}AB=3m matches RQ=3mRQ = 3 \, \text{m}RQ=3m

    BC=4mBC = 4 \, \text{m}BC=4m matches PR=4mPR = 4 \, \text{m}PR=4m

    AC=5mAC = 5 \, \text{m}AC=5m matches PQ=5mPQ = 5 \, \text{m}PQ=5m

    The corresponding sides of the two triangles are equal.

    Therefore, the two triangles are congruent by SSS Congruence.

    Thus, the correct order of congruency is:

    △ABC≅△PRQ\triangle ABC \cong \triangle PRQ△BCA△RPQ

    So the correct answer is (d)
