## gaara438125 3 years ago proofs...really suck

1. gaara438125

14. a 15. b 16. c 17. d 18. e

2. AriPotta

all proofs start with the same thing, so a and b would be...?

3. gaara438125

given, i know that xD

4. AriPotta

ok, just making sure lol

5. AriPotta

ummm. now that i'm looking at it.....i'm not quite sure what to put....

6. gaara438125

i know angle 2 is congruent to angle 4 .....ugh lol it's so obvious stuff just don't what the answer would be

7. Fall12-13

I still didn't understand how are we supposed to solve the question. Do you need to label it like 1-2-3 ?

8. AriPotta

you have to list the justifications for the statements in the boxes

9. sara12345

c. by Definition of Supplementary Angles

10. sara12345

or c. supplementary angles add up to 180

11. sara12345

both wil work

12. sara12345

d. by Definition of same-side interior angles

13. gaara438125

that's seriously all i have to put for d...?

14. AriPotta

but i don't see how you can state that they're same-side interior angles without proving that the lines are parallel

15. sara12345

e. Converse of same-side interior angles theorem

16. sara12345

yes, anything more than that would be irrelevent/redundant for d.
