I really need help with this portion of my homework. People have given me answers, but NOT for sure if they are right. I will give you a Medal if you help me. The answer & explanation has to be correct and accurate, because my teacher said it has to be. Label your answer and your postulate/theorem, so I know which is which. ***The next section instructions are: Determine whether each statement is true or false. Justify your response with the appropriate postulate or theorem.***

My Answers: 8. True, because the lines aren't parallel 9. False, because the lines aren't parallel 10. True, because of the corresponding angle theorem 11. ? 12. ? 13. False, because the lines aren't parallel. 14. False, because the lines aren't parallel.

jimthompson5910 (jim_thompson5910):

8 is true, but that's not the reason why

jimthompson5910 (jim_thompson5910):

9 is false, but which two lines aren't parallel? you need to be specific

jimthompson5910 (jim_thompson5910):

10 is true and the reason is good

jimthompson5910 (jim_thompson5910):

how about 11?

OpenStudy (firejay5):

what's #8's reason and #9's specifics

OpenStudy (firejay5):

@jim_thompson5910 For 8 I said,: True, because they add up to 180 degrees + because of consecutive interior angle theorem.

jimthompson5910 (jim_thompson5910):

#8 would actually be the same side interior angle theorem

OpenStudy (firejay5):

#9 would be line m and n

jimthompson5910 (jim_thompson5910):

what about them?

OpenStudy (firejay5):

they aren't parallel or perpendicular

jimthompson5910 (jim_thompson5910):

lines m and n aren't parallel, so that's why

OpenStudy (firejay5):

11, I say True

jimthompson5910 (jim_thompson5910):

sounds like a guess, why do you say true?

OpenStudy (firejay5):

they are alternate interior angles

jimthompson5910 (jim_thompson5910):

but you said so yourself that m and n aren't parallel

OpenStudy (firejay5):

@jim_thompson5910 Is this #11: True, because lines m and n aren't parallel + because of alternate interior angles

jimthompson5910 (jim_thompson5910):

alternate interior angles are only congruent if the lines are parallel

OpenStudy (firejay5):

so just lines m and aren't parallel for the reason for #11

OpenStudy (firejay5):

so is that it for #11. If so, let's move on to #12

jimthompson5910 (jim_thompson5910):

#11 is false for that reason, yes

OpenStudy (firejay5):

So #11 is False, because lines m and n aren't parallel

jimthompson5910 (jim_thompson5910):

yes

OpenStudy (firejay5):

#12: True, because of same side interior angles

OpenStudy (firejay5):

#13 & #14 I said False, because m and n aren't parallel

jimthompson5910 (jim_thompson5910):

the reason is correct, but because they are same side interior angles does not guarantee congruence

OpenStudy (firejay5):

so should I keep the reason or not keep it

jimthompson5910 (jim_thompson5910):

I'd keep the reason, just change the statement

OpenStudy (firejay5):

like how would I do that

jimthompson5910 (jim_thompson5910):

well you would start off saying it's false, then explain that it's false because the fact that they are same side interior angles doesn't guarantee congruence

OpenStudy (firejay5):

What' about #13 and #14: I said False, because line m and n aren't paralle

jimthompson5910 (jim_thompson5910):

yep, both are false because m and n aren't parallel once they aren't parallel, you can't use any to the parallel theorems you've learned

OpenStudy (firejay5):

so is that okay for my reason for 13 and 14

OpenStudy (firejay5):

Uh @jim_thompson5910 so are my reason for 13 and 14 passable; anymore information I need to add

jimthompson5910 (jim_thompson5910):

hmm nothing that I can think of at the moment

OpenStudy (mathstudent55):

Do you know that lines l and m are parallel? I don't see it as given information anywhere.

OpenStudy (firejay5):

click on 2nd link and it'll be on there

OpenStudy (mathstudent55):

Oh, I see, the line at the top.
