    If \[\Delta ABC\cong \Delta DEF\] by S.S.S. congruence rule, which of the following options holds true?

    A) \[\angle A>\angle D\]

    B)        \[\angle A=\angle D,\,\,\angle B=\angle E,\,\,\angle C=\angle F\]

    C)        \[\angle B<\angle E\]

    D)        \[\angle C=\angle F\]

    Correct Answer: B

    Solution :

    Given, \[\Delta ABC\cong \Delta DEF\]by S.S.S. Congruence \[\Rightarrow \]\[\angle A=\angle D\] \[\angle B=\angle E\] \[\angle C=\angle F\][Corresponding parts of congruent triangles.]
