Number of Edges on a Cone

How many edges does a cone have?


A cone has one edge. This, however, is only applicable in terms of the polyhedral definition of an edge as ‘˜a straight line that is the intersection of two faces of a solid figure’™, or in terms of plane geometry where an edge is ‘˜a boundary of a plane geometric figure’™. In loose, general terms, a one-edged cone is also accepted. This is according to Doctor Peterson of the University of Drexel’™s the Math Forum.
