Answer 1

The correct option about the proof is C. Both Amanda and Stephen are correct.

How to illustrate the information?

It should be noted that both Amanda and Stephan are correct as they are taking two different pairs of supplementary angles.

Amanda's proof is that he takes (∠1 and ∠4) and (∠3 and ∠4)as the supplementary angles and writes ∠1 + ∠4 = 180° and ∠3 + ∠4 = 180°,

Stephan's proof is that he takes (∠1 and ∠2) and (∠3 and ∠4) as the supplementary angle pair.

Therefore, the correct option is C.
