![]() We define rounded solid shapes as solid shapes that have at least one curved face. Octagonal prism: each base has the shape of an octagon.Hexagon prism: each base is in the shape of a hexagon. ![]() Pentagonal prism: each of the bases is in the shape of a pentagon.Quadrangular prism: each of the bases is in the shape of a quadrilateral.Triangular prism: each base is shaped like a triangle.The polygon found at the base determines the name of the prism, for example: if the bases are triangles it is a triangular prism.Īccording to the base, the prism can be named as: These parallelograms are called lateral faces of the prism, and the two remaining polygons are called bases. The remaining faces of the prism are parallelograms that have common sides with these polygons. PrismsĪ prism is a polyhedron, two of its faces are equal and lie in parallel planes. Of the two resulting pieces, the lower part is a truncated pyramid and the upper part remains a pyramid. This polyhedron is obtained by sectioning a pyramid with an intermediate plane parallel to its base. The number of faces is the same as the number of edges of the bases. On the other hand, it is composed of lateral faces in the shape of a trapezoid. The frustum of a pyramid is a type of polyhedron composed of two parallel bases with the same number of edges. These are the triangular pyramid or tetrahedron, the cube, the octahedron, the dodecahedron and the icosahedron. The five convex examples have been known since ancient times and are called Platonic polyhedra. Ī convex polyhedron is a polyhedron that materializes a convex solid, that is, for each pair of points in the solid, the linear segment that joins them is completely contained in the solid. There are a total of nine regular polyhedra: five convex polyhedra and four star polyhedra. ![]() Regular polyhedra are the most symmetrical. These solid shapes can be classified according to the number of faces. Regular polyhedra are made up of regular polygons. In three-dimensional geometry, a polyhedron is the equivalent of any polygon in two-dimensional geometry. Among them, we can distinguish regular polyhedra and irregular polyhedra. Polyhedra are a particular case of solid shapes whose faces are all polygons. In addition to their importance in geometry and mathematics, solid shapes are used in practical applications in architecture, design, and science, serving as essential tools for conceptualizing and modeling objects in the three-dimensional world. Geometric bodies encompass various shapes, from prisms and pyramids to spheres and cylinders, each with unique properties.įlat faces, sharp edges, and connected vertices contribute to the characterization of these solids in three-dimensional space. ![]() Differentiating themselves from two-dimensional figures, these three-dimensional solids have faces, edges and vertices that define their structure. What Is a Solid Shape?Ī solid shape is a three-dimensional entity that occupies space in the dimensions of height, width and depth. The diversity of solid shapes, from pyramids to cylinders, allows us to model and understand the richness of shapes that we find in the three-dimensional world that surrounds us. The importance of these three-dimensional geometric figures lies in their ability to describe real and abstract objects in space, being crucial in fields such as architecture, design and engineering.Ī classic example is the cube, with its six square faces and connected vertices, which represents an elementary geometric solid. These solids, defined by faces, edges and vertices, play a fundamental role in the conceptualization and understanding of three-dimensional structures. In geometry, solid shapes constitute an essential category of three-dimensional shapes that occupy space in three dimensions: height, width and length.
