/kärˈtēZHən kōˈôrdəˌnāts/
noun: Cartesian coordinate; plural noun: Cartesian coordinates
Numbers which indicate the location of a point relative to a fixed reference point (the origin), being its shortest (perpendicular) distances from two fixed axes (or three planes defined by three fixed axes) which intersect at right angles at the origin.
The image above shows a three-dimensional Cartesian coordinate system with origin O and axis lines X, Y, and Z, oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinates x = 2, y = 3, and z = 4, or (2, 3, 4).
