In a 3D Cartesian system, what is the name of the point where X, Y, and Z axes intersect?

• A. Origin in the Cartesian coordinate system
• B. Center point of the cube
• C. Intersection of planes
• D. Node of axes

Answer: (A)

The point where the X, Y, and Z axes meet is called the origin. In 3D Cartesian coordinates, it serves as the reference starting point for the entire space, with coordinates (0, 0, 0). This point is the intersection of the three coordinate planes (the XY plane with z = 0, the XZ plane with y = 0, and the YZ plane with x = 0), which is why all three coordinates are zero there. It’s the universal reference from which distances along each axis are measured. Terms like the center of a cube or a generic “node of axes” aren’t standard names for this intersection in the coordinate system.
