HERE IS YOUR ANSWER :-
As D and E are mid-points of sides AB and BC of the triangle ABC, by Theorem 1,
DE || AC
Similarly, DF || BC and EF || AB
Therefore ADEF, BDFE and DFCE are all parallelograms.
Now DE is a diagonal of the parallelogram BDFE,
therefore, ∆ BDE ≅ ∆ FED
Similarly ∆ DAF ≅ ∆ FED
and ∆ EFC ≅ ∆ FED
So, all the four triangles are congruent.
