The question is "Lines 's' and 't' intersect, and line 'v' does not intersect either one." (I draw it)

That is logically impossible...

If two lines are intersecting each other, they must be at different angles. The definition of a line says that lines go on infinitely. Therefore I can't make a line that doesn't intersect the other lines, correct?

Example: ( v | ) Those three 'lines' will eventually intersect because they go on infinitely.

Same with v and ( + \ ).

Every possible explanation is invalid. So what the heck do I put on my paper?

try thinking of them as line segments instead of lines perhaps?

But the book just says 'lines' and nothing more. But I guess that's all I can do.

draw them on a scale or something..

If it doesn't tell you that the lines are infinite then don't assume that.

If they are infinite then it's impossible since they would form a virtual planar. If they are finite then it is possible.

i wish i was smart i would have answered that

I hate this kind of math. When will we ever use this in real life?

When you are stuck in an elevator with a paper and pencil for weeks.

You never know... being able to know if a point is coplaner or not could some day save my life.

Did imy answer help at all lol?

I did what Flame told me to do, which was pretty much what you said. It was a little late.

Oh sorry. As I said I won't really be active these days as much.
