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.
