B
С
Which of these could be a step to prove that BC2 = AB2 + AC2? (6 points)
O By the addition property of equality, Ac? plus AD2 = AB multiplied by DC plus AD2.
O By the addition property of equality, ACplus AD2 = BC multiplied by DC plus AD2.
By the addition property of equality, AC2 plus AB2 = AB multiplied by DC plus AB2.
O By the addition property of equality, AC2 plus ABP = BC multiplied by DC plus AB2.
