Quandaries and Queries


I was wondering about the intersection of planes. Can planes intersect?




Hi Joshua,

In the room where you are sitting there are many pieces of planes. The floor and ceiling are pieces of parallel planes. These planes do not intersect. The East wall and the South wall are pieces of two planes that do intersect. The intersection is the line that forms the South-East corner of the room. The East wall, South wall and floor are three planes that intersect at one point, the point on the floor in the South-East corner of the room.
