    \[\Delta \,ABC\cong \Delta FDE\] What is the measure of \[\angle F\]?

    A)  \[50{}^\circ \]    

    B)  \[60{}^\circ \]           

    C)  \[80{}^\circ \]                      

    D)  \[75{}^\circ \]

    Correct Answer: A

    Solution :

    (a): They are congruent \[\Rightarrow \,\,\,\angle A=\angle F;\]Now \[\angle A=180{}^\circ -60{}^\circ -70{}^\circ =50{}^\circ \] \[\therefore \,\,\,\angle F=50{}^\circ \]
