Question

Given: ΔABC is a right triangle.
Prove: a2 + b2 = c2


The following two-column proof with missing justifications proves the Pythagorean Theorem using similar triangles:

Answer 1

Which is not a justification for the proof?
Pieces of Right Triangles Similarity Theorem
Side-Side-Side Similarity Theorem
Substitution
Addition Property of Equality

Answer 2

I don't think it is A

Answer 3

would it be C. substitution?

Answer 4

the proof uses substitution

Answer 5

it uses addition property of equalities

Answer 6

doesnt it use pieces of right triangle similarity t as well

Answer 7

I have not heard of a theorem named that. Have you been taught that one ?
I know we have the answer narrowed down to 2 choices.

Answer 8

this is like a slideshow i found about it http://www.slideshare.net/teacherfidel/right-triangle-similarity

Answer 9

Its basically splitting up the triangle

Answer 10

i mean its used in the first part i believe but i dont know about the proofs section...

Answer 11

I find some of these questions to be quite tricky sometimes

Answer 12

i guess it would be B...
