Triangles.
Triangle (tetrahedron, octahedron, icosahedron) Square (cube) Pentagon (dodecahedron)
They are both 3 dimensional shapes with faces that are polygons.
The three types of polygons that can be the faces of a Platonic solid are equilateral triangles, squares, and regular pentagons. These polygons must be regular, meaning all sides and angles are equal. The unique arrangement of these faces gives rise to the five distinct Platonic solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Each solid has faces that are identical and meet at each vertex in the same way.
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.

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.

Equilateral triangles
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).
There is no simple answer to this question.Polyhedra are named according to the number of faces that they have. An icosahedron is a 3-dimensional shape with 20 faces. It could be in the form of a pyramid with a 19-sided polygon as base. In that case, it has 20 vertices. Or it could be in the form of a prism with 18-sided polygons as base and in that case it has 36 vertices. There are several million different configurations, and the number of vertices varies.The regular icosahedron is a Platonic solid with faces that are equilateral triangles. That has 12 vertices.

regular pentagons.... Kyah!
20 faces
