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:
““I see nobody on the road,” said Alice.
“I only wish I had such eyes,” the King remarked in a fretful tone. “To be able to see Nobody! And at that distance too! Why, it’s as much as I can do to see real people, by this light!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
