How many edges does a cone have?


Quick Answer

In strict geometric terms, a cone does not have any edges. Since a cone lacks a plane and an edge in geometry is the location where two planes intersect, it does not have any edges.

Full Answer

However, the answer to this question depends on the definition of "edge" and "plane." If it is considered that the cone has an infinite amount of intersecting planes, there are an infinite number of edges where each of these planes intersect with each other. If one considers the term "edge" to mean the boundary of a geometric plane figure, then a cone has one edge along the perimeter of its flat base.
