Introduction to Three Dimensional Geometry
Three Dimensional Geometry Coordinate Axes In three-dimensional geometry, the x-axis, y-axis and z-axis are the three coordinate axes of a rectangular Cartesian coordinate system. These lines are three mutually perpendicular lines. The values of the coordinate axes determine the location of the point in the coordinate plane.
Three Dimensional Geometry Coordinate Planes The three planes (XY, YZ and ZX) determined by the pair of axes are the coordinate planes. All three planes divide the space into eight parts, called octants.
