What is the point where the three linear axes X, Y, and Z intersect in a Cartesian coordinate system?

• A. Origin in the Cartesian coordinate system
• B. Center of the coordinate system
• C. Zero point in polar system
• D. Node of axes

Answer: (A)

In a 3D Cartesian coordinate system, the three axes X, Y, and Z meet at a single reference point called the origin. This point has coordinates (0, 0, 0), meaning zero along each axis. The origin serves as the baseline from which every position is measured: moving along one axis changes only that coordinate while the others remain zero. Other terms like “center” aren’t the standard way to name this point, and a polar zero refers to a different coordinate system (r = 0) rather than the intersection of Cartesian axes.
