because f = r, m = m, and Both have congruent 90degree angle

Answer 6

But idk I oculd be wrong.

Answer 7

Okay, you're wrong. You cant say that f=r by SAS because it is not a triangle if you see step 5 it says triangle NRM is congruent to triangle EFD by SSS. What they did in step 4 is they used the square root property of equality to cancel the squared in step 3.
