The undefined term that can contain parallel lines is "plane." In geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions. Within a plane, parallel lines are defined as lines that never intersect and are always the same distance apart. Thus, a plane can accommodate multiple sets of parallel lines.
The pair of undefined terms used to define parallel lines is "line" and "point." Parallel lines are defined as two lines in a plane that do not intersect, regardless of how far they are extended, and a point is used to describe the position relative to these lines. These terms are foundational in geometry, serving as the basis for more complex definitions and theorems.
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Skew lines are a term for lines in geometry. They mean two lines that are not parallel, but do not intersect either. It is only possible in three dimensions and up.
A set can be defined or undefined.

Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
If they intersect they are refered to as skew lines and if the do not the term for this is that they are parallel lines.

Two opposite sets of parallel lines.
A set can be defined or undefined.
A ray is not an undefined term.
Latitude and LongitudeLatitude is the lines that go from east to west, and longitude from north to south.
Parallels.An easy way to remember this is by remembering that lines of lattitude run parallel across the earth.
