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; (6 points)
by the addition property of equality, ac2 plus ad2 - ab multiplied by dc plus ad2
by the addition property of equality, ac? plus ad2 - bc multiplied by dc plus ad2
by the addition property of equality, ac2 plus ab2 - ab multiplied by dc plus ab
by the addition property of equality, ac plus ab2 - bc multiplied by dc plus ab2,
