D, E and F are th

Answer :


Given, D, E and F are mid-points od sides BC, CA and AB, respectively.


So, EF||BC and by Mid-Point Theorem,


DF||AC and DE||AB


Also, EF = BC, DE = AB and FD = AC


Since, ABC is an equilateral triangle,


AB = BC = AC



DE = EF = FD


Thus, all sides of ΔDEF are equal.


Hence, ΔDEF is an equilateral triangle.
