B. Yes, they are congruent, if three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent by (Side-Side-Side ) (SSS)
[tex]\begin{gathered} AB\cong FD \\ BC\cong ED \\ AC\cong FE \end{gathered}[/tex]C. Congruent shapes have identical measurements and coincide with each other when superimposed. Similarity means closely resembling each other but not quite the same. The difference in size aspect means that a similar shape can never be congruent.
