A Cartesian coordinate system in the space consists of number lines (axes) perpendicularly intersecting in one point called the origin. The orientation of the axes is chosen according to the ,,Right-Hand-Rule`` as shown in the figure.

A point is determined by the values - called the coordinates - obtained by perpendicular projection of the point onto the axes: . Using a notation without subscripts, the coordinates are usually symbolized by and the number axes are called -, - and -axis.

A Cartesian coordinate system in the plane is defined in an analogous manner.
