D, E, F are the mid points of the sides BC, CA and AB respectively of △ ABC. Then △ DEF is congruent to triangle –
ABC
AEF
BFD, CDE
AFE, BFD, CDE
It is easy to verify that △ DEF is congruent to each one of the triangles △ AFE, △ BFD & △ CDE
D, E, F are the mid points of the sides BC, CA and AB respectively of an equilateral △ ABC. Then △ DEF is congruent to triangle –
