A pyramid
A solid cannot be bounded by one polygon. A solid bounded by polygons is called a polyhedron.
Polygon
equilateral triangles and regular pentagons
The main difference between a polygon and a solid shape is that polygons are two dimensional. In contrast, solid shapes are three dimensional objects.
Equilateral triangles, squares, regular pentagons.
A pyramid.
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
