Intersection of Two PlanesDate: 9/3/95 at 13:17:50 From: jeremy Subject: geometry What is the intersection of two planes? Date: 9/4/95 at 11:58:47 From: Doctor Ken Subject: Re: geometry Hello! When two planes intersect, they can do one of two things: a) if they're parallel and there are any points in the intersection at all, then the intersection has to be the whole plane. b) if they're parallel, they don't have to intersect at all. c) if they're not parallel, the intersection will always be a straight line. Most planes aren't parallel, so they'd intersect in a line. - Doctor Ken, The Geometry Forum |
