polyhedron
vertex
A plane vertex is a point where two lines meet or intersect. A point has no size so the adjectine "large" is irrelevant".
A point.
true
A solid body standing on a triangular, square, or polygonal base, and terminating in a point at the top; especially, a structure or edifice of this shape., A solid figure contained by a plane rectilineal figure as base and several triangles which have a common vertex and whose bases are sides of the base., The game of pool in which the balls are placed in the form of a triangle at spot.

There two different shapes that have more than one vertex. One is a triangle it is a plane figure that has three straight sides and three angles and a quadrilateral which a four sided figure.
The line or plane upon which a geometric figure is thought of as resting is called the base. A three-dimensional figure with a circular base and the top meeting at a vertex; it resembles a funnel cone.
The solid A described is a type of three-dimensional geometric figure known as a pyramid. Specifically, it consists of a polygonal base (the polygon) and a vertex (the point) that lies above the plane of the base. All points between the polygon and the vertex form the volume of the pyramid, which tapers from the base to the apex. The shape and size of the pyramid depend on the specific polygon chosen and the location of the apex relative to the base.
A pyramid has a single polygonal face as its base.
A heptagon has seven polygonal faces - sides that are plane.
