A three dimensional plot with the point
\(P\) labeled and drawn with a green segment parallel to the z-axis. The green segment is labeled 2. A red segment is drawn perpendicular to the x-axis to the end point of the green segment on the xy-plane. The red segment is labeled 3. A blue segment goes from the origin to the point at which the green segment hits the xy-plane and is labeled 5.
