A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Because they lie on parallel planes, which share the same normal vector, the distance between the skew lines at their closest point can be calculated as the scalar projection of a vector pointing from one line to another onto the common normal vector. By definition parallel lines are lines in a plane which do not meet, that means, they have to be coplanar. The lines on a notebook are coplanar to each other. a. Below are four terms that describe different ways coplanar lines may interact: Parallel lines, segments, or rays: Lines that run in the same direction and never cross (like two railroad tracks) are called parallel.
