## What is a Euclidean line?

A Euclidean line is a flat, infinitely large one-dimensional space following the laws of Euclidean geometry. It is often mistaken for a line segment, which is a connected subset of the line of finite length with two points as its boundary.

How do you define a line?

In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points.

### What is the definition of a line in mathematics?

Line, Basic element of Euclidean geometry. Euclid defined a line as an interval between two points and claimed it could be extended indefinitely in either direction. Such an extension in both directions is now thought of as a line, while Euclid’s original definition is considered a line segment.
