    A In \[\Delta ABC\] and \[\Delta PQR,\] \[AB=x\text{ }cm,\] \[BC=y\text{ }cm\]and \[CA=z\text{ }cm\]. What are the measures of sides PQ, QR and RP of \[\Delta PQR\] if \[\Delta ABC\cong \Delta ABC\cong \Delta PQR\]?

    A)
    PQ QR RP
    x cm y cm z cm
     

    B)
    PQ QR RP
    y cm x cm z cm

    C)
    PQ QR RP
    x cm z cm y cm

    D)
    PQ QR RP
    z cm x cm y cm

    Correct Answer: A

    Solution :

     Corresponding parts of congruent triangles are equal. So, \[PQ=AB=x\text{ }cm,\] \[QR=BC=y\text{ }cm\] and \[RP=CA=z\text{ }cm\].
