Question

(will attach problem)??

Which is NOT a justification for the proof?

A. Addition Property of Equality
B. Pythagorean Theorem
C. Pieces of Right Triangles Similarity Theorem
D. Cross Product Property

Answer 1

i think the answer is C? but this is sort of confusing so I am not sure if I am right

Answer 2

@Callisto can you help? :)

Answer 3

for sure its not A or B, as you're using addition property of equality for (a^2+b^2 = cy+b^2)

and obviously last row, you have to put Pythagorean theorem

so its not A or B

Answer 4

yeah those are the two i eliminated because of those reasons

Answer 5

il go wid C. i never heard of such a theorem. google also never heard of it.

Answer 6

yeah thats why i thought it was C. just making sure someone else agreed :) would you mind helping me out with another problem? ive done most of it but I am stuck on one part. I will post it as a new question.

Answer 7

sure :)

Answer 8

On second thoughts :
answer is B

Answer 9

becoz, we are proving pythagorean theorem here. So we CANNOT use the same in it lol. it looks silly now.... btw last row justification is property of exponents :) good luck...
