How to square the two sides of a triangle

The sum of the squares of the two sides of a triangle is equal to twice the sum of the squares of half the squares of the third side and the median line on that side
That is: ab & # 178; + AC & # 178; = 2 [(BC / 2) &# 178; + AD & # 178;] [D is the midpoint of BC]
