Line Segments, Parallel, Perpendicular or Neither
Geometry-Parallels and PolygonsDownloadable Video - 2014
In this video we'll learn how to determine whether two line segments are parallel, perpendicular, or neither. If they're parallel, they'll have the same slope. If they're perpendicular, their slopes will be the negative reciprocals of one another. If neither of these is the case, then the line segments are neither parallel nor perpendicular.
