In geometry, the perpendicular distance from a point, P, to a line, L, is the distance from P to L, measured along a line which is perpendicular to L and passes through P.
In three dimensions, a perpendicular distance may also be the distance from a point to a plane, measured along the line that passes through the point and is perpendicular to the plane. Also, it can be the distance between two non-coplanar lines, measured along the line that has perpendicular intersections with them both.

Famous quotes containing the word distance:
“By sharing the information and observations with the caregiver, you have a chance to see your child through another pair of eyes. Because she has some distance and objectivity, a caregiver often sees things that a parent’s total involvement with her child doesn’t allow.”
—Amy Laura Dombro (20th century)
