# rectangular coordinate system

## Definition

### Electronics

- Also called Cartesian coordinate system. A
__coordinate system__ in which the locations of points are given in reference to the __axes__, numbering two or more. Each of these coordinate axes is perpendicular to the others, and all intersect at a common point called the origin. Each coordinate axis, or Cartesian axis, represents a __plane__ called a __Cartesian plane__. A number of lines, __equal__ to the number of planes, may be drawn from the origin to any given point on a plane or in space, and the exact location of this point can be specified by giving the coordinates with respect to the axes.
