Question

what is the reason for the last step in given proof?

Substitution property of equality

linear pair theorem

congruent supplements theorem

transitive property of equality

For parrallel lines cut by a transversal, corresponding angles are congruent.

Answer 1

@Krissy1997 are you good at proofs?

Answer 2

Semi yes

Answer 3

can you help me?

Answer 4

i'll try

Answer 5

thanks so much I was thinking it was Linear pair theorem

Answer 6

did they give you oppinses.... sorry i can't spell

Answer 7

up top in my question is the choices

Answer 8

i think it is Linear pair theorem

Answer 9

can you have a linear pair on a different transversal plane?

Answer 10

i mean i liked at all the angles the others statements on the graph and looked at the reasons.... and angles JIK and IJL have the same measurement

Answer 11

so would that make them congruent?

Answer 12

Sorry Im really confused not sure if Linear has to be 90 degrees if so then these angles are not

Answer 13

kinda yes and not really not trying to confuse you though

Answer 14

so which one do you think it is

Answer 15

linear pair theorem

Answer 16

thank you!!!
