Triangles.
Triangle (tetrahedron, octahedron, icosahedron) Square (cube) Pentagon (dodecahedron)
They are both 3 dimensional shapes with faces that are polygons.
A platonic solid is characterized by having identical faces that are regular polygons. There are five types of platonic solids: the tetrahedron (triangular faces), cube (square faces), octahedron (triangular faces), dodecahedron (pentagonal faces), and icosahedron (triangular faces). Each type has faces that are congruent and meet at the same angle, ensuring uniformity in their geometric structure.
Icosahedron are a shape with 20 faces, 30 edges and 12 vertices. All the faces are triangles.
You need to find the area of each of its faces and add them together. An icosahedron may or may not have parallel faces. For example, an icosahedron, in the form of a pyramid with a 19-gon base will have no parallel faces.
Triangle (tetrahedron, octahedron, icosahedron) Square (cube) Pentagon (dodecahedron)
They are both 3 dimensional shapes with faces that are polygons.
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
They are both simply connected 3-dimensional shapes, all of whose faces are polygons.

regular pentagons.... Kyah!
An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles). A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).
