Question

In $	riangle ABC$ with sides $a, b, c$ opposite to vertices $A, B, C$ and medians $d, e, f$ from $A, B, C$ respectively, $d^2 =$

Accepted Answer

$\dfrac{2(b^2+c^2) - a^2}{4}$

Answer

$\dfrac{2(a^2+c^2) - b^2}{4}$

Answer

$\dfrac{2(a^2+b^2) - c^2}{4}$

Answer

$\dfrac{a^2+b^2+c^2}{4}$

In △ABC\triangle ABC△ABC with sides a,b,ca, b, ca,b,c opposite to vertices A,B,CA, B, CA,B,C and medians d,e,fd, e, fd,e,f from A,B,CA, B, CA,B,C respectively, d2=d^2 =d2=
