What problem would there be in your picture if the line were not parallel?

Answer 1

Parallel means lines that are avoiding each other (in other words, they don't touch.) So the problem would have to be the way the lines are going. If the lines were intersecting (or crossing) then that would be the problem.

For example: You have a problem on a paper that asks you this same question:

What problem would there be in your picture if the lines were not parallel?

Answer: Then your lines would be an intersecting pair.

Slight definition: If your lines are not parallel, then they would have to be intersecting. Intersecting is when two lines (line segments, angles, etc.) cross on each other. For example... they might make an X by forming together in this pattern. Parallel is when your lines are NOT touching. If they are, they would be considered our P/Intersecting. Standing for "Parallel and Intersecting lines."

SRW!!

Answer 2

You would get what is called barrel distortion.
