What is a skew line?

A skew line is a pair of non-intersecting lines that do not lie in the same plane. This means that they are not parallel, as parallel lines lie in the same plane. Skew lines have no points in common and they do not intersect even when extended infinitely. Skew lines are always found in three-dimensional space and cannot exist in two-dimensional space. They provide a different perspective on the relationship between lines compared to parallel or intersecting lines.
