Here the last alphabets of the alphabetical series are taken or the first alphabets of the word is taken to represent the coordinates of a point.Ī coordinate is an address, which helps to locate a point in space. The origin is denoted by the O and the coordinates of a point is denoted by the point (x, y, z). The examples of a point in a three-dimensional frame is (2, 5, 4). The points in a cartesian coordinate system are written in parentheses, and separated by a comma. Notation of a point in a cartesian coordinate system is a way of presenting a point for easy understanding and calculations. Similar to the two-dimensional coordinate system, here also the point of intersection of these three axes is the origin O, and these axes divide the space into eight octants. The three-dimensional cartesian coordinate system consists of three axes, the x-axis, the y-axis, and the z-axis, which are mutually perpendicular to each other and have the same units of length across all three axes. The coordinates of any point in three-dimensional geometry have three coordinates, (x, y, z). The 3d geometry helps in the representation of a line or a plane in a three-dimensional plane, using the x-axis, y-axis, z-axis.
