    In the given figure, line PRT is parallel to SQN. If \[RS=8\text{ }cm\] what is the length of RO?

    A)  7 cm                          

    B)  3 cm        

    C)  4 cm         

    D)  6 cm

    Correct Answer: C

    Solution :

    (c): \[\Delta POR\cong \Delta QOS\] (by ASA congruency) since \[\angle RPO=\angle SQO:\angle POR=\angle QOS\] and \[PO=OQ\] \[\therefore \,\,\,\,\,RO=SO=\frac{1}{2}RS=4\,cm\]
