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?

3. Gabylovesyou

AAS postulate Pythagorean Theorem (I think) (maybe) Triangle Proportionality Theorem SSS postulate

4. Honstine

Triangle Proportionality Theorem is the correct way of doing it

5. Gabylovesyou

wow i suck okay thank you

6. phi

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

7. Gabylovesyou

so i was right ?

8. phi

9. Gabylovesyou

mine is B

10. Honstine

i used Triangle Proportionality Theorem but Pythagoras is one way

11. phi

oh, yes, that is correct

12. Gabylovesyou

i dont know which answer to put now

13. Gabylovesyou

B ?

14. Gabylovesyou

@phi

15. phi

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

16. Gabylovesyou

ok
