Skew Lines

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:

    When first my lines of heavenly joys made mention,
    Such was their luster, they did so excel,
    That I sought out quaint words and trim invention;
    My thoughts began to burnish, sprout, and swell,
    Curling with metaphors a plain intention,
    Decking the sense as if it were to sell.
    George Herbert (1593–1633)
