## Definitions

#### Diameter➦

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.

#### Dimension➦

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one (1D) because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.

#### Diameter➦

A straight line segment passing through the center of a figure, especially of a circle or sphere, and terminating at the periphery.

#### Dimension➦

A measurable extent of a particular kind, such as length, breadth, depth, or height
