Definition
Skew lines are two lines
in space that do not
intersect but are not
parallel.

Common Perpendiculars (CP)
Piercing Points
What is a piercing point?
Piercing points are nonparallel lines running
through and intersecting a plane. They define
the place on the plane where a line intersects
it.
