Antonyms of “intersection ” [closed]

There are two places you're most likely to find intersections: in math class(Discrete Math Concept) and in traffic. In math, an intersection is the spot where two lines cross. Those lines share this common point. The center of the letter X is an intersection. The same is true for streets.

What are the near antonyms of intersection for a math and traffic concepts?

I think the antonym will describe something "out of intersection" or those not intersect with the referenced "thing".

Is there a word suitable as an antonym to intersection ?

The closest word I found was "disjoint", "disjointed".

PS:

"Antonyms are only significant when it is a binary word. Antonym is a binary concept. And two non-intersecting lines are parallel only in Euclidean plane geometry; not in solid geometry, and not in non-Euclidean geometry. There is no simple antonym without an equally simple context, which must be presupposed."

Yes, it seems even something dummy(to not say stupid) try to get a word(or words) with the opposite meaning of a non-binary word, who would want to set a non-apple?

The objective of my question is to find some word to clear (self explanatory) give a name for a program method to get an object that doesn't intersect this thing.

I'm just looking forward to find another word to represent "non-intersection".

Solution 1:

This is not a single word, but in mathematics, conceptually you are after the symmetric difference:

In mathematics, the symmetric difference, also known as the disjunctive union, of two sets is the set of elements which are in either of the sets and not in their intersection.

The reference article provides a nice illustration:

For traffic or roads, I thought about roundabout, which is a way to get to a cross street without a direct intersection, or a track, which is a closed circuit used for racing, thus theoretically lacks an intersection.
