A three-dimensional figure with a polygon base and triangular faces that meet at a common vertex is called a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the apex is the common vertex where all the triangular faces converge. Pyramids are named based on the shape of their base, such as triangular pyramids or square pyramids.
No. All pyramids have four or more vertices (because a triangular pyramid has four).
