D, E and F are the mid point of sides BC , CA,AB of a triangle ABC 1

1.	D, E and F are the mid point of sides BC , CA,AB of a triangle ABC 1. BDEF is a parallelogram 2. ar(DEF)=14ar(ABC) 3. (BDEF)=12ar(ABC)
Answer» D, E and F are the mid point of sides BC , CA,AB of a triangle ABC 1. BDEF is a parallelogram 2. $a r (D E F) = \frac{1}{4} a r (A B C)$ 3. $(B D E F) = \frac{1}{2} a r (A B C)$
