A polygon is a 2-dimensional figure bounded by three or more straight lines. Any one of its sides may be considered a base.
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, a square pyramid is not a polygon; it is a three-dimensional geometric figure. A polygon is a flat, two-dimensional shape with straight sides, such as a triangle or a square. In contrast, a square pyramid has a square base and four triangular faces that converge at a point above the base, giving it volume and depth.

A polygon is a 2-dimensional figure bounded by three or more straight lines. Any one of its sides may be considered a base.
A polyhedron is a three-dimensional figure formed by flat surfaces that are bounded by polygons joining along their sides (the faces of the polyhedron).A circle is not a polygon, but we can say that a circle is the limit of a regular polygon with n sides. It means that if n becomes larger and larger, the polygon shape approaches to a circle. A circle is a two dimensional figure as a polygon is, but a three dimensional figure whose base(s) is/are a circle cannot be called a polyhedron.

No. Polyhedra are three-dimensional objects, and the base of any prism, strictly speaking, should be two-dimensional. Any convex polygon (which is two-dimensional) can form the base of a pyramid. A circle, which is technically not a polygon, is the only convex two-dimensional figure that cannot form the base of a pyramid because it forms the base of a cone.
No, a square pyramid is not a polygon; it is a three-dimensional geometric figure. A polygon is a flat, two-dimensional shape with straight sides, such as a triangle or a square. In contrast, a square pyramid has a square base and four triangular faces that converge at a point above the base, giving it volume and depth.
Tetrahedron
Because the base of a cone is round, it is the only three dimensional figure with only one vertex.

A cylinder is a basic geometric three dimensional figure. The base is a circle. A cylinder can be described as an enclosed tube. It cannot be classified as a polygon since all of the sides are not segments.
