Dimensions
On the most basic level, this term refers to the measurements describing the size of an object. For example, length and width
are the dimensions of a rectangle.
In a more advanced sense, the number of dimensions a set, region,
object, or space possesses indicates how many mutually perpendicular directions of
movement
are possible.
For
example,
a line is one
dimensional, a plane is two
dimensional, the space in which we
live is three
dimensional, and a point is zero
dimensional.
