Question

Need some help on this question.

Answer 1

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

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

*picture here*

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


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