WebJan 11, 2024 · A Platonic solid is a regular, convex polyhedron in a three-dimensional space with equivalent faces composed of congruent convex regular polygonal faces. The five solids that meet this criterion are the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Some sets in geometry are infinite, like the set of all points in a line.

WebMar 24, 2024 · The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons. There are exactly five such solids (Steinhaus 1999, pp. 252-256): the cube, dodecahedron, icosahedron, octahedron, and tetrahedron, as was proved by Euclid in the last proposition …
WebApr 3, 2024 · So, there is no general formula for finding the surface area of a regular polyhedron. Note:There are some properties of a regular polyhedron as: -The vertices of a convex regular polyhedron all lie on a sphere. -All the dihedral angles of the polyhedron are equal. -All the polyhedrons consisting of vertex figures are regular polygons. http://www.seas.ucla.edu/~vandenbe/ee236a/lectures/polyhedra.pdf
