This is a tetrahedron, which has four congruent equilateral triangles as its faces.

 

 

This is a hexahedron (cube), which has six congruent squares as its faces.

 

 

This is an octahedron, which has eight congruent equilateral triangles as its faces.

 

 

This is a dodecahedron, which has twelve regular pentagons as its faces.

 

 

This is an icosahedron, which has twenty equilateral triangles as its faces.
