Distance

 

distance in depth between servicemen, guns, vehicles, and subunits or units (ships) when formed in ranks, on the march (cruise), or in combat formation and also between aircraft when flying in formation or in a combat formation.


Distance

 

an important geometric concept whose meaning depends on the kind of entities for which it is defined. The distance between two points is the length of the line segment joining the points. The distance from a point to a line or a plane is the length of the perpendicular from this point to the line or plane. The distance between two parallel lines or planes is the length of a common perpendicular to the lines or planes. The distance between two nonintersecting nonparallel lines in space is equal to the distance between the parallel planes in which the lines lie—that is, the length of the line segment that joins the lines and is perpendicular to both.
