Step-by-step explanation:

THIS IS WORTH 15 POINTS BECAUSE OF IMPROPER ANWSERS FOR POINTS BUT WILL GIVE BRAINLIEST IF CORRECT
Anarel [89]

Answer:

  C. Only Henry's proof is correct.

Step-by-step explanation:

Amy's "proof" leaves out the steps that Henry's proof puts in. Only Henry's proof is correct.

__

Amy's proof has no reasoning to support her "therefore ..." and no reasoning to support her conclusion that angles 4 and 2 are equal. Nothing in her proof supports her conclusion that the transitive property of equality can be applied.
