Two non-parallel lines in 3D-space that do not intersect.

Normal to 2 skew lines

Similar to Normal to 2 lines — Straight Lines.

Distance between 2 skew lines

distance=ABn\text{distance}=\lvert{\overrightarrow{AB}\cdot\underline{n}}\rvert

Here

  • n\underline{n} is the unit normal to both l1,l2l_1,l_2
  • AA and BB are points lying on each line
