Find the length of the mid segment (median)

Apollonius’s Theorem states that “the sum of the squares of any two sides of a triangle equals twice the square on half the third side and twice the square on the median bisecting the third side”.

From the above figure, According to Apollonius’s Theorm we have:  

b^{2} + c^{2} = 2*(a^{2}+m^{2})    

where a, b, and c are the length of sides of the triangle  

and m is the length of median of the triangle on side 2*a
