In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons (all angles congruent and all edges congruent), and the same number of faces meet at each vertex.
Platonic solids are regular, convex polyhedrons in 3D with equivalent faces. There are 5 types of platonic solids. Learn all about the interesting concept of platonic shapes, their properties, its types along with solving examples.
A Platonic Solid is a 3D shape where: each face is the same regular polygon. the same number of polygons meet at each vertex (corner) Example: the Cube is a Platonic Solid. each face is the same-sized square. 3 squares meet at each corner. There are only five platonic solids.
Apr 30, 2024 · Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron.
Aug 3, 2023 · Platonic solids, also known as regular solids or regular polyhedra, are 3-dimensional solids consisting of convex, regular polygons. As it is a regular polyhedron, each face is the same regular polygon, and the same number of polygons meets at each vertex.
3 days ago · The Platonic solids, also called the regular solids or regular polyhedra, are convex polyhedra with equivalent faces composed of congruent convex regular polygons.
Aug 24, 2021 · Regular polyhedra are also called Platonic solids (named for Plato). If you fix the number of sides and their length, there is one and only one regular polygon with that number of sides. That is, every regular quadrilateral is a square, but there can be different sized squares.
There are 5 "Platonic solids" that were identified by the Greek mathematician Plato. They are three dimensional solids ( polyhedra) having the following properties: The faces of the shape are regular polygons. That is, they have all sides and interior angles equal. All the faces are congruent. That is they are all identical in shape and size.
Polyhedra with these two properties are called Platonic solids, named after the Greek philosopher Plato. So what do the Platonic solids look like – and how many of them are there? To make a three-dimensional shape, we need at least faces to meet at every vertex. Let’s start systematically with the smallest regular polygon: equilateral triangles:
The ancient Greek mathematician Euclid proved in his Elements of Geometry that there are only five Platonic solids – the regular tetrahedron (four sides that are equilateral triangles), the cube (six sides that are squares), the regular octahedron (eight sides that are equilateral triangles), the regular dodecahedron (twelve sides that are regul...
