## Definition

The process of extending a straight line segment is called **production**.

Such a straight line segment is said to be **produced**.

The line segment can be extended in either direction, thus producing an infinite half-line, or in both directions, thus producing an infinite straight line.

In the words of Euclid:

*To produce a finite straight line continuously in a straight line.*
