Rectangular Coordinates is also known as the Cartesian coordinate system. After Descartes popularized its use in analytic geometry http://www.brainpop.com/math/geometryandmeasurement/coordinateplane/ click this link to watch a video.. [] click this link to do an activity..

A ** coordinate ** is a number that determines the location of a point along some line or curve. Two, three, or more ** coordinates ** can be used to determine the location of a point on a **Surface**, ** Volume **, or higher-** Dimension **domain. For example, the ** Longitude ** is a coordinate which determines the position of a point along the **Earth's** **Equator**, and ** Latitude ** is another coordinate that defines a poisition along a ** Meridian **. The pair of coordinates consising of a latitude and a longitude determines a point on the surface of the ** Earth **.

A systematic method of assigning such a coordinate list to each point in the domain is called a ** Coordinate System **. There is an infinitude of coordinate systems that one could define for any domain, and many that are used in specific contexts. The usual latitude-longitude coordinate system, for example, is widely used in ** Geography ** and ** Astronomy **. The ** Cartesian Coordinates ** for the ** Euclidean plane ** and ** Euclidean space ** is the basis of ** Analytic Geometry **.

Coordinates are typically named after the system used to assign them; thus one says "the Cartesian coordinates of a point //p//" to mean "the coordinates assigned to //p// by a Cartesian coordinate system".

In the two-dimensional Cartesian coordinate system, a point P in the //xy//-plane is represented by a pair of numbers (//x//,//y//). In the three-dimensional Cartesian coordinate system, a point P in the //xyz//-space is represented by a triple of numbers (//x//,//y//,//z//). [|mysite.du.edu/~jcalvert/ math/groupdum.htm]
 * //x// is the signed distance from the //y//-axis to the point P, and
 * //y// is the signed distance from the //x//-axis to the point P.
 * //x// is the signed distance from the //yz//-plane to the point P,
 * //y// is the signed distance from the //xz//-plane to the point P, and
 * //z// is the signed distance from the //xy//-plane to the point P.
