A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.
A polyhedron of which one face is a polygon of any number of sides, and the other faces are triangles with a common vertex.
A polyhedron of which one face is a square, and the other faces are triangles with a common vertex.
Triangle
The shapes that have 3 sides and 3 vertices are called triangles. Triangles are classified based on the lengths of their sides and the measures of their angles. The three most common types of triangles are equilateral triangles (all sides and angles are equal), isosceles triangles (two sides and two angles are equal), and scalene triangles (all sides and angles are different).
A prism has two identical polygonal bases connected by rectangular or parallelogram faces, so it has 2 sides. A pyramid has a polygonal base and triangular faces that meet at a common vertex, so it has a total of n+1 sides, where n is the number of sides of the base polygon.

pyramid An pyramid is a geometric solid of the shape made famous by the royal tombs of ancient Egypt. It is a solid whose base is a polygon and whose lateral faces are triangles with a common vertex
A polyhedron of which one face is a polygon of any number of sides, and the other faces are triangles with a common vertex.
Both are basic geometric figures. A polygon is a 2-dimensional area enclosed by straight lines. A polyhedron is an analogous figure in 3-dimensional space, but they do not have all that much in common.A polyhedron is bounded by polygons, not straight lines.
