What does "alternate" mean?

OpenStudy (anonymous):

idk

OpenStudy (tkhunny):

Does it mean "same side" or "opposite sides"? What do you suppose?

OpenStudy (anonymous):

same

OpenStudy (tkhunny):

"alternate" - No, it's different. If you take an "alternate" route, is that the same road you would have taken or some different road? There are two sets of alternate external angles. 1 & what? 2 & what?

OpenStudy (anonymous):

1&7 2&8

OpenStudy (tkhunny):

There you have it. Find them in the answer section.

OpenStudy (anonymous):

OpenStudy (tkhunny):

D. ∠2 and ∠7 Which of 1&7 or 2&8 is that? It looks like neither, to me.

OpenStudy (tkhunny):

There you go. Now, move on to the next one with a little more confidence.
