@iambatman

OpenStudy (zzr0ck3r):

How many planes does a triangle live in?

OpenStudy (calculusxy):

One?

OpenStudy (zzr0ck3r):

yes

OpenStudy (zzr0ck3r):

same thing here. If you take a line and the some point not on that line. It can only live in one plane.

OpenStudy (zzr0ck3r):

For the same reason that a triangle can live in at most one plane.

OpenStudy (zzr0ck3r):

then*

OpenStudy (calculusxy):

When would it lie in multiple planes?

OpenStudy (zzr0ck3r):

Think about drawing a line in front of you in the air. Now put a point next to it (but not on it). How many angles can you put a piece of paper in the air so that it has the line and point?

OpenStudy (calculusxy):

In several angles I think.

OpenStudy (calculusxy):

Can you make sure some other fill-in-the-blanks with "always", "sometimes", or "never"? @zzr0ck3r

OpenStudy (calculusxy):

Adjacent angles are "sometimes" congruent

OpenStudy (zzr0ck3r):

Just like you can only have the triangle in one plane, same thing here.

OpenStudy (calculusxy):

So am I correct?

OpenStudy (zzr0ck3r):

what was your answer again?

OpenStudy (calculusxy):

"sometimes"

OpenStudy (zzr0ck3r):

it will always lie in a plane

OpenStudy (calculusxy):

For what question?

OpenStudy (zzr0ck3r):

but NEVER more than one

OpenStudy (calculusxy):

Ok. Yes I got that already.

OpenStudy (zzr0ck3r):

oh lol

OpenStudy (calculusxy):

What about: Adjacent angles are "sometimes" congruent. Is that correct?

OpenStudy (zzr0ck3r):

I see. Close this question and open a new one.

OpenStudy (calculusxy):

OK
