Icosahedron is a polyhedron with 20 faces, each of which is an equilateral triangle. It is one of the five Platonic solids, which are convex polyhedra with identical faces and identical vertices. The icosahedron has 12 vertices and 30 edges. It is dual to the dodecahedron, meaning that the vertices of one correspond to the faces of the other, and vice versa.
The icosahedron can be found in various contexts, including mathematics, chemistry, and architecture. In mathematics, it
The icosahedron can be inscribed in a sphere, with each vertex touching the sphere. This sphere is
The icosahedron has several interesting properties, including its symmetrical arrangement of faces and vertices, its role
