In solid geometry, skew lines are two lines that do not intersect and are not parallel. Equivalently, they are lines that are not coplanar. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Lines that are coplanar either intersect or are parallel, so skew lines exist only in three or more dimensions.

Famous quotes containing the word lines:
“We joined long wagon trains moving south; we met hundreds of wagons going north; the roads east and west were crawling lines of families traveling under canvas, looking for work, for another foothold somewhere on the land.... The country was ruined, the whole world was ruined; nothing like this had ever happened before. There was no hope, but everyone felt the courage of despair.”
—Rose Wilder Lane (1886–1968)
