One of them is a tetrahedron i think? i dunno? wot else is there?
(don't get confused)
the 5 regular:
tetrahedron (triangular pyramid) face:4 edge:6 verticies:4 dual: tetrahedron
cube (triangular deltohedron) face:6 edge:12 verticies:8 dual: octohedron
octohedron (square dipyramid) face:8 edge:12 verticies:6 dual: cube
dodecahedron (I think:half truncated pentagonal deltohedron) face:12 edge:30 verticies:20 dual: icosahedron
icosahedron (penagonal gyrolongated dipyramid) face:20 edge:30 verticies:12 dual: dodecahedron
there is an unlimited number, but these are the regular ones, wich means all faces, edges, and verticies are the same.
(circles, cones, and spheres are not polyhedrons because they'r not flat)

Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
What geometric shape are dice?
Polyhedrons.
What are polhedrons?
Polyhedrons are shapes with many faces
Some polyhedrons are neither prisms nor pyramids?
true
Cones and polyhedrons both have only one base?
false
