A system in which points on a plane are identified by an ordered pair of numbers, representing the distances to two or three perpendicular axes.

A coordinate system in which the locations of points in space are expressed by reference to three planes, called coordinate planes, no two of which are parallel. The three planes intersect in three st [..]

A system in which points on a plane are identified by an ordered pair of numbers, representing the distances to two or three perpendicular axes.

a pair of numerical coordinates which specify the position of a point on a plane based on its distance from the the two fixed perpendicular axes (which, with their positive and negative values, split [..]

are a system of positional reference in which location is measured along two or three orthogonal (perpendicular) axes. Every location can be defined uniquely by its X, Y, and Z coordinates. Locations in the coordinate system can be established using any unit of measurement such as meters, feet, and miles. Cartesian coordinates differ from latitude- [..]

a system whereby points on a plane are identified by an ordered pair of numbers, representing the distances to two or three perpendicular axes. The standard "x-y" coordinate system used in high school algebra is a Cartesian Coordinate System ... with points in the plane having Cartesian coordinates (x, y). center

Coordinates that differ from latitude-longitude coordinates in that the latter comprise a spherical (rather than planar) reference system.

A system of uniquely marking the position of a point on a plane [or in 3-dimensional space] -- by 2 [3] numbers (its "cartesian coordinates") giving its distances from 2 [3] mutually perpend [..]

Coordinates that differ from latitude-longitude coordinates in that the latter comprise a spherical (rather than planar) reference system.

(US) Cartesian coordinates|lang=en

Cartesian coordinates (x, y, or x, y, z; also known as rectangular coordinates) are directed distances from two (or three) perpendicular axes.
