Which set of terms states that Z, Y, and X form right angles with each other?

Which set of terms states that Z, Y, and X form right angles with each other?

• A. Polar coordinate axes
• B. Cartesian coordinate system axes
• C. Cylindrical coordinate axes
• D. Spherical coordinate axes

Answer: (B)

The important idea is using three perpendicular directions to locate a point in 3D. In a Cartesian coordinate system, the X, Y, and Z axes stand at right angles to each other, forming an orthogonal set. That perpendicular arrangement lets you specify a point with three independent measurements along each axis. Other coordinate systems describe position with combinations of a radius and angles (like r, theta, z or r, theta, phi), which do not form three fixed, mutually perpendicular axes in space. So the statement describes Cartesian coordinate system axes.
