Yes, those are the three possibilites, provided both lines are on a plane.

In the drawing below I have shortened the lines so they look like segments to beter fit them on a screen. Remember as lines they continue on forever.

So they can and cant? depending on the point or direction ?

On a plane. They can be parallel and never meet. They can intersect at 1 point. They can be the same line ( on top of each other ) and intersect at an infinite number of points.

Parallel postulate talks about parallel lines never crossing.

I am really having trouble answering this question

If I have two lines, will they cross? Explain fully. What postulate helps me answer this question?
