Intersecting.
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!

If an object is symmetrical, it means that both sides are equal in size. In the word WHISPER, the letter H and the letter W both have symmetrical sides.

Perpendicular
cords, lines
The letter is "q" The word is "queue" They are pronounced exactly the same.
Either not at all, or at exactly one point. There's no other possibility.
Parallel lines are two lines which travel in exactly the same direction, or have exactly the same 2d gradient. This means that they would never touch, even if continued to infinity. Parallel planes are planes which travel in exactly the same direction, or have exactly the same 3d gradient. This means that they too would never touch, even if continued to infinity. The fact that they would never touch means that they cannot intersect at any place, so the number of intersections is 0.
A four letter word that means winner can be hero, but it does not exactly mean winner.
