Answer 1

When you use more than one reference direction to describe an object's position, you are using two **coordinate axes**. In a two-dimensional space, for example, this typically involves using a vertical axis (y-axis) and a horizontal axis (x-axis) to specify the location of the object using a coordinate pair (x, y). In three-dimensional space, a third axis (z-axis) is added, resulting in a coordinate triplet (x, y, z). These reference directions help in accurately describing the position of objects in the defined space.
