    By which congruency criterion, \[\Delta PQR\cong \Delta PQS\]?       

    A)  RHS                          

    B)  ASA   

    C)         SSS               

    D)         SAS

    Correct Answer: C

    Solution :

    In \[\Delta PQR\]and \[\Delta PQS\] \[PR=PS=a\text{ }cm\] (given) \[RQ=SQ=b\text{ }cm\] (given) \[PQ=PO\](common) \[\therefore \]  \[\Delta \,PQR\cong \Delta SQR\] (By SSS) \[\Rightarrow \]  \[\Delta PQR\cong \Delta PQS\]
