Question

Provide the reasons for the proof.
Given: m 12 years ago

Answer 1

I meant:
m<1 = m< 2

Answer 2

Statement:
<1 is supplementary to <2

Reason:
??

Answer 3

Their non-common sides are opposite rays

Answer 4

Would that be the reason for <1 is supplementary to <2?
@Mertsj

Answer 5

That was the statement you posted and asked for the reason. What else would it be the answer to?

Answer 6

Then what would the reason for m<1 + m<2 = 180 degrees?
And how do you figure this out?

Answer 7

That way I can figure the rest.

Answer 8

Look at you list of theorems. You just said that the angles are supplementary. What does that mean?

Answer 9

It means the two angles sum up to 180 degrees, I get that.
What I am lost at is, do you have to state all theorems in your reasons or could you say anything there?

Answer 10

Anyways, not any of these are rays like what you said.
