Lines and line segments that lie on the same plane (and consequently space) are considered coplanar lines. Thus, two parallel lines sometimes coplanar. True or False: Two lines that are parallel to each other have negative reciprocal of the slopes. 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. u(0)=5,u(0)=3,v(0)=1,v(0)=2. $\overline{ST}$ and $\overline{UV}$ are coplanar.
