    Two satellites are being launched such that their distance while moving in their respective orbits, are equal from Earth and Moon.                                   Which of the following statements is/are true?

    A)  Figure X is not congruent to figure Y.

    B)  \[\angle 1\] and \[\angle 2\] are not equal.

    C)  Both (a) and (b)

    D)  None of these

    Correct Answer: D

    Solution :

    In \[\Delta PQR\] and \[\Delta SQR\]       \[PQ=QS\](given)             \[PR=SR\] (given)           \[QR=QP\] (common)     \[\therefore \] \[\Delta \,PQR\cong \,\Delta SQR\] (By SSS)  X    \[\Rightarrow \]  \[\angle 1=\angle 2\](By CPCT)
