Parallel lines are lines that will never intersect, even if they [continue on forever] (I admit, I'm not entirely sure on that last part, since there might be something different.)
Lines that are not parallel will cross. We say that they will intersect, and we call the point an intersection.
You can think of angles as [a fragment of intersecting lines].
Sorry I couldn't be of much help, but I think there are quite a few possible answers to this haha
