(mathematics) The coordinates of a point in a plane, measured as its Cartesian distance from the origin and the angle measured anticlockwise/counterclockwise from the x-axis to a line joining the point to the origin.

(geometry) The coordinates of a point measured from an origin along a horizontal axis from left to right (the x-axis) and along a vertical axis from bottom to top (the y-axis). This can be extended to three-dimensions by the z-axis perpendicular to the x- and y-axes.

(British spelling) Designed to have matching colours.

(American spelling) Alternative form of color coordinated

(geometry, mathematical analysis) A method of representing the position of any individual point in a space of given dimensionality as a tuple of numerical coordinates.

Alternative form of coordination compound

(US) Alternative letter-case form of Cartesian coordinates

(chiefly in the plural) Any coordinate in a three-dimensional coordinate system used to map the universal locations of structures in the human brain.

plural of Talairach coordinate

(geometry) Any one of a set of n + 1 coordinates which non-uniquely identify a point in an n-dimensional projective space; when such coordinates are all multiplied by the same scalar, then the set of them still identifies the same point.
