cone
A cone has one vertex, one edge, and one base.

When a square pyramid is sliced perpendicular to its base through a vertex, the cross section will be a triangle. This triangle will have one vertex at the apex of the pyramid and the other two vertices on the base, forming a triangular shape that includes one of the pyramid's edges and a segment of the base. The resulting triangle will be isosceles if the slice is made symmetrically.
A cross section of a rectangular pyramid through its vertex and perpendicular to its base creates a triangular shape. This triangle's base corresponds to one of the edges of the rectangular base, while its apex is at the vertex of the pyramid. The height of the triangle is determined by the vertical distance from the vertex to the base.
The solid shape you are describing is called a cone. A cone has a circular base and narrows to a single vertex, or apex, at the top. Its curved surface connects the base to the vertex, distinguishing it from other solid shapes.

A two-faced object with one vertex is a shape known as a "cone." A cone has a circular base, which is one face, and a pointed tip at the top, which is its vertex. The other face is the curved surface that connects the base to the vertex. Thus, it effectively has two distinct faces: the base and the curved surface.
The shape described is a cone. A cone has a circular base and a single vertex where the curved surface converges. The surface extends from the base to the vertex, forming a pointed top. Cones can be found in various contexts, such as ice cream cones and traffic cones.
