What is the missing step in the proof?
A) Statement: ∠GAC and ∠GAB are supplementary.
Reason: Linear Pair Theorem
B) Statement: ∠AFE≅∠AFD
Reason: Transitive Property of Equality
C) Statement: ∠GAC≅∠BAF
Reason: Vertical Angles Theorem
D) Statement: ∠GAC and ∠AFD are supplementary.
Reason: Linear Pair Theorem

Alright, I would have thought so too..

- Baseballguy101

i can't say 100% but i would go with b

B? alright!

This one is pretty big.. I do not like this one.

Here's the choices for option one.

- xapproachesinfinity

ok so we want to prove that those congruent angle are 90
we have by the transverse two parallel lines
the angle GAC is congruent to EFG
and by the supplementary angles on a line EFG+AFD=180
but AFD is congruent to GAC
so we have EFG=90
therefore the line is perpendicular
and also it must be perpendicular to both line since they are parallel

Infinity, Baseball kinda already helped me answer that one.. lol..

- Baseballguy101

im not the best at proofs but to me the last choice is the one one that makes sense. xapproachesinfinity looks to know a lot more about it than me haha

Perhaps you two should work together on this? I don't have that much time left to work on this, sadly...

- Baseballguy101

ok what are the second options?

- anonymous

Here you go.

Ugh, I have to leave soon, but I will return to doing this at home, but that doesn't mean I'll get the same questions.. :/

- Baseballguy101

that one is linear pair
