Given: 5 years ago

Answer 1

or NONE OF THESE

Answer 2

this is confusing to me- my textbook doesnt really cover it

Answer 3

@geerky42 ????

Answer 4

@Directrix ?????

Answer 5

Looking at the two proof options, @Joshyface , are angles H and E vertical angles or are they exterior angles?

Answer 6

vertical angles

Answer 7

@Joshyface Yes, and vertical angles are congruent.

The two given proofs lack, in my opinon, all the necessary steps. However, one of them has the key steps and that may be what is being asked. The proof with the vertical angles is the one that makes sense. As you pointed out, angles H and E are not exterior as they are stated to be in the second proof.
So, which proof is it?

Answer 8

@Joshyface

Answer 9

would it be "none of these"?

Answer 10

or mc0057?

Answer 11

mc0057 has the vertical angle step

Answer 12

@Joshyface My teacher would not accept either of the two given proofs because steps are missing. The second proof contains a wrong statement so it is out.

The key steps of the first proof are correct. I don't know what your teacher requires. But, I'd go with the first and hope for the best.
