"Zero latitude" is the line closest to the equator, because it's the definition of the equator itself.
Once you leave the equator, there's no such thing as the "closest line". Any parallel of latitude
you draw, no matter how close it is to the equator, I can always draw one that's closer. There's
no 'official' set of lines. You can draw as few or as many lines as you want, wherever you want them.
Lines of latitude are parallel to the equator, and that includes the Arctic and Antarctic Circles. The Tropics of Cancer and Capricorn are also parallel to the equator.See the link below
They are lines of constant latitude, all parallel to the equator.
there are two names i can think of: lines of latitude and also parallels
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
That line has often been called the "Equator" in song and story, and on maps as well, too.

A single line cannot be perpendicular or parallel. These are attributes of two (or more) lines.

A trapezoid has one pair of parallel lines.
One side cannot be parallel because parallel is a relationship between two lines (or sides). A square has two pairs of parallel lines.
Lines of latitude run round the earth parallel to the Equator. Lines of longitude run from pole to pole, crossing the Equator at 90 degrees.
Two lines are coplanar iff they are parallel OR intersect.
The equator
The equator or any of the lines of longitude (which meet at the poles).
There is no intersection. These two imaginary lines are parallel. Every point on the Tropic of Cancer is 23.5 degrees from the equator, no more and no less. The lines don't meet.
When two lines are parallel, then they do not intersect.
