Question

Which Theorem justifies this conclusion?


Given:

Measure of angle 1 + measure of angle 2 = 180º
Measure of angle 2 + measure of angle 3 = 180º
Conclusion:

angle 1 is congruent to angle 3

Congruent Supplements Theorem
Linear Pair Theorem
Congruent Complements Theorem
Definition of Supplementary Angles

Answer 1

The first choice

Answer 2

why

Answer 3

@Evoker

Answer 4

That theorem says if two angles are supplements of the same angle they are congruent.

Answer 5

what about congruent Complements Theorem

Answer 6

@eriyalovesu please msg me back :)

Answer 7

That would work if they both added to 90

Answer 8

@Evoker

Answer 9

oh!!

Answer 10

whats uh.. going on here?

Answer 11

trying to figure out why it would be one and not the other.
I now agree with @Evoker that it would be congruent supplements

Answer 12

i see

Answer 13

thanks y'all
