Parallel and Perpendicular Lines. Parallel lines. are two lines that, if extended indefinitely, would never cross or touch. A point is an exact location in space.. You are here.. A true point has no length, no width, and no height.. In fact, you cannot see a true point.. A point is named by a letter.. P. Point P. Lines are 1-dimensional objects that have only length. Lines continue forever in both directions.. EXAMPLE 1. Identify relationships in space. d.. Plane. (. s. ). parallel to plane . EFG. . and containing point . A. c.. Line. (. s. ). perpendicular to .
