Question

Answer 1

Statement Reason
1. r2 = m2 + n2 Given
2. f2 = m2 + n2 ?
3. f2 = r2 Substitution
4. f = r Square Root Property of Equality
5. Triangle NRM is congruent to triangle EFD SSS Postulate
6. Angle NRM is a right angle CPCTC
7. Triangle NRM is a right triangle Angle NRM is a right angle

Which reason best fits statement 2?

Answer 2

AAS postulate

Pythagorean Theorem (I think) (maybe)

Triangle Proportionality Theorem

SSS postulate

Answer 3

Triangle Proportionality Theorem is the correct way of doing it

Answer 4

wow i suck okay thank you

Answer 5

If you make a right triangle, you can say
\[ 2. f^2 = m^2 + n^2 ? \]
because of pythagoras

Answer 6

so i was right ?

Answer 7

I do not see your answer.

Answer 8

mine is B

Answer 9

i used Triangle Proportionality Theorem but Pythagoras is one way

Answer 10

oh, yes, that is correct

Answer 11

i dont know which answer to put now

Answer 12

B ?

Answer 13

@phi

Answer 14

yes. The reason you can say f^2 = m^2 + n^2 is because you can use the pythagorean theorem

Answer 15

ok
