Consider you have two lines are very close to each other, but they are not as if one line is 100 percent exactly on the other line. In other words, suppose that we have picture and if zoom in and zoom out on the graph, we would have something like below:
Now my question is which phrase should be used to describe this two lines the best if we are in the zoom-out perspective as well as when we are in the two-times-zoomed-in perspective. I've only come up with
- the overlapping two lines
- the coinciding two lines
However, in reality we know they are not 100 percent overlapping. They just happen to be two parallel lines that are very close to each other.
