Anotations

Scope note:

In mathematics, the trace of a moving point in continuous extent, either straight or curved, having length but without breadth or thickness. In geometry, the concept of a line can vary with the definition of geometry; for example in analytic geometry, a line is the set of points on a plane having coordinates that satisfy a given linear equation; in incidence geometry, a line may be an independent object distinct from the set of points which lie on it.
