Question

D, E, F are the midpoints of sides BC, CA, AB of $	riangle ABC$ respectively. Then $\vec{AD}+\vec{BE}+\vec{CF}=$

Accepted Answer

$\vec{0}$

Answer

$\vec{AB}$

Answer

$\vec{BC}$

Answer

$\vec{AB}+\vec{BC}+\vec{CA}$

D, E, F are the midpoints of sides BC, CA, AB of △ABC\triangle ABC△ABC respectively. Then AD⃗+BE⃗+CF⃗=\vec{AD}+\vec{BE}+\vec{CF}=AD+BE+
