parallel lines never touch, never get any closer or any further apart.
tangent lines touch at one point

A circle does not have a set of parallel lines in the traditional sense, as parallel lines are defined as lines that never intersect and remain equidistant from each other. However, you can draw lines that are tangent to a circle at various points, and these tangent lines can be parallel if they are at the same distance from the center of the circle. But in the context of the circle itself, it does not contain parallel lines.
Non-parallel lines intersect at some point, parallel lines don't.
A secant line touches a circle at two points. On the other hand a tangent line meets a circle at one point.
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
