Question

.

Answer 1

Im not that great at proofs, but how much more do u need??

Answer 2

Ok, give me a moment...

Answer 3

thank you so much @nikato !!!!!

Answer 4

sorry....://

Answer 5

Ok, so <1 and 2 are supplementary and so are 3 and 4, right?

Answer 6

And by CPCTC <1=<3

Answer 7

I think those angles are supplementary by definition of supplementary. Then after u say those angle are congruent by CPCTC, u can use the supplement theorem

Answer 8

U can use CPCTC again. Or u can combine the steps

Answer 9

5. 1=3. cPCTC
6. 1 and 2 are supplementary. 3 and 4 are supplementary. Def. of supplementary
7. Therefore 2=4. Supplement theroem

Answer 10

Yea

Answer 11

But if u want, u can combine steps 4 and 5, becuz they use the same reason

Answer 12

Yea, that's it. U proved what u needed to prove.

And no, 5 is CPCTC

Answer 13

sorry i combined 4 and 5 to 4 so i meant would 6 be supplement theorem? no right

Answer 14

Oh, if that's the case, the next step would be definition of supplementary . The next and final would be supplement theroem

Answer 15

Yea, no problem
