Three
Dimensions The property of the space in which we live and move that indicates motion can take place in three mutually perpendicular directions. This is often expressed with three-dimensional coordinates. Formally, saying a space has three dimensions means that you can find three vectors in the space for which none is a linear combination of the other two. In addition, in any set of four vectors one of them can be written as a linear combination of the other three.
