Distance Between Parallel Lines: Lesson (Geometry Concepts)

Discover more at www.ck12.org: http://www.ck12.org/geometry/Distance-Between-Parallel-Lines/.

Here you’ll learn that the shortest distance between two parallel lines is the length of a perpendicular line between them.

This video gives more detail about the mathematical principles presented in Distance Between Parallel Lines.
