### What do you understand by Three-Dimensional Geometry?

To locate position of an object in a line, you just need the distance of the object from the point of reference. To locate the position of a point in a plane, we need two intersecting mutually perpendicular lines in the plane. These lines are called the coordinate axes and the two numbers are called the coordinates of the point with respect to the axes. The point O is called the origin of the coordinate system. The three coordinate planes. These three coordinate planes divide the space into eight parts known as octants.
