If two sides and the included angle of one triangle are congruentto the corresponding parts of another triangle, the triangles are congruent.
Since:
[tex]\begin{gathered} AC\cong DF \\ \angle C\cong\angle F \end{gathered}[/tex]
Then, in order to the triangles be congruent:
[tex]BC\cong EF[/tex]
Answer:
A
