Lines and Planes
Two planes are said to be parallel if their normal vectors are parallel. A line L is said to be parallel to a plane p if the direction vectors of L are perpendicular to the normal vectors of p. Two planes are said to be perpendicular if their normal vectors are perpendicular. A line L is said to be perpendicular to a plane p if the direction vectors of L are normal to p. Figure 10.5.9 illustrates these definitions.
A line which is not parallel to a plane will intersect the plane at exactly one point.
Two planes which are not parallel intersect at a line.
