ikozaéderes

An ikosaéderes is a three-dimensional geometric shape. It is one of the five Platonic solids, distinguished by its regular faces and vertices. Specifically, an ikosaéderes is a polyhedron composed of twenty identical equilateral triangles. Each vertex of an ikosaéderes is shared by five of these triangular faces. This regularity gives the ikosaéderes a high degree of symmetry. It possesses sixty edges and twelve vertices. The word "ikosaéderes" originates from the Greek words "eikosi" meaning twenty, and "hedra" meaning seat or face. Its dual polyhedron is the dodecaéderes, which has twelve pentagonal faces. The ikosaéderes can be inscribed within a sphere, and its vertices all lie on the surface of that sphere. It is also possible to circumscribe a sphere around an ikosaéderes, such that the sphere is tangent to all of its edges. Examples of objects that approximate the shape of an ikosaéderes include some viruses and certain crystal structures.
