Answer 1

When you use more than one reference direction to describe an object's position, you are using two **coordinate axes** or **reference frames**. This typically involves a two-dimensional (2D) or three-dimensional (3D) system, where multiple directions (such as x and y in 2D, or x, y, and z in 3D) are utilized to specify the position of an object.
