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.

The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC.

Which of these could be a step to prove that BC2 = AB2 + AC2? (6 points)

By the addition property of equality, AC2 plus AD2 = AB multiplied by DC plus AD2.
By the addition property of equality, AC2 plus AD2 = BC multiplied by DC plus AD2.
By the addition property of equality, AC2 plus AB2 = AB multiplied by DC plus AB2.
By the addition property of equality, AC2 plus AB2 = BC multiplied by DC plus AB2.
