Definition:Linear Measure/Length

Definition
Length is distance measured in one direction.

Usually, in multi-dimensional figures, the dimension in which the distance is greatest is referred to as length.

It is the most widely used term for linear measure, as it is the standard term used when only one dimension is under consideration.

Length is the fundamental notion of Euclidean geometry, never defined but regarded as an intuitive concept at the basis of every geometrical theorem.
