Hillary is using the figure shown below to prove Pythagorean Theorem using triangle similarity: In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.

Which of these could be a step to prove that BC2 = AB2 + AC2?
a) By the addition property of equality, AC2 plus AD2 = AB multiplied by DC plus AD2.

b) By the addition property of equality, AC2 plus AD2 = BC multiplied by DC plus AD2.

c) By the addition property of equality, AC2 plus AB2 = AB multiplied by DC plus AB2.

d) By the addition property of equality, AC2 plus AB2 = BC multiplied by DC plus AB2.
Can someone help me out? Thanks :)
