OpenStudy (derpisthewordorisit):
I think it's A.
OpenStudy (dangerousjesse):
Firstly, do you know what exterior angles are?
OpenStudy (derpisthewordorisit):
2lines that cross.
OpenStudy (dangerousjesse):
No, that's the definition of intersecting lines :)

OpenStudy (derpisthewordorisit):
OH EXTERIAL, I thought you said alternate lines
OpenStudy (derpisthewordorisit):

Those are exterior angles, the ones marked A and B
OpenStudy (derpisthewordorisit):
I'm not sure which one is the answer but I believe it's A, C and D look the same.
OpenStudy (dangerousjesse):
Now, do you know what alternate means?
OpenStudy (derpisthewordorisit):
Yes
OpenStudy (derpisthewordorisit):
When 2 lines cross another line

No, alternate means opposite
OpenStudy (dangerousjesse):
Now, tell me the two pairs of angles that are exterior and on opposite ends and sides of the line?
OpenStudy (derpisthewordorisit):
Not quite sure, I suck at these. I'm looking at a book and I'm still confused.
OpenStudy (dangerousjesse):

OpenStudy (derpisthewordorisit):
So I'm suggesting it's A since they are like that.

That's one type of pair
OpenStudy (dangerousjesse):
|dw:1450458353868:dw|
OpenStudy (dangerousjesse):
That's another
OpenStudy (dangerousjesse):
Now, which two pairs match?
