Word definition(s)

In geometry, the adjective parallel refers to a coplanar straight lines, or planes, having no common point, or a due curve, which maintain the constant distance at each point. For the extension the term applies to everything that extends and proceeds in the same direction as another entity, respect for this always the same distance.

Word origin

The meaning of parallel is connected to Euclid's definition of straight lines p. in a plane, according to which two are parallel if two of their prolonged parts never meet. To indicate that two straight lines r, s are p., We use to write rs (we read: r is p. A s); similarly between two floors or between straight line and floor. Two coincident spaces are also considered parallel
