Question

Example of perpendicular axes in cartesian coordinate system

Answer 1

In three-dimensional space, the Cartesian coordinate system is based on three mutually perpendicular coordinate axes: the x-axis, the y-axis, and the z-axis, illustrated below. The three axes intersect at the point called the origin.

Answer 2

An example is ( x,y ) = (2,-5). The origin is usually, but not always, assigned the value (0,0). Cartesian three-space, also called xyz -space, has a third axis, oriented at right angles to the xy plane. This axis, usually called the z axis, passes through the origin of the xy -plane.
