Question

PLEASE HELP!!!!!!
Hillary is using the figure shown below to prove Pythagorean Theorem using triangle similarity:

In the given triangle ABC, angle A is 90 degrees and segment AD is perpendicular to segment BC.

Which of these could be a step to prove that BC^2 = AB^2 + AC^2?

Answer 1

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

By the addition property of equality, AC^2 plus AD^2 = AB multiplied by DC plus AD^2.
By the addition property of equality, AC^2 plus AD^2 = BC multiplied by DC plus AD^2.
By the addition property of equality, AC^2 plus AB^2 = AB multiplied by DC plus AB^2.
By the addition property of equality, AC^2 plus AB^2 = BC multiplied by DC plus AB^2.

Answer 9

Addition Property of Equality
For real numbers a, b, and c, if a = b, then a + c = b + c.

Answer 10

I don't know the actual answer, but as far as any guess goes, I'm going to say it's: C.
I'm sorry I couldn't be of more help to you.
