Polygons and their names

Just for fun:

I think I fixed the 3-d issue... Let me know...

Polygon =/= Polyhedron

Those are indeed the names of the polygons, closed plane figures bounded by straight lines.

They are not the names of the polyhedrons, solids formed by plane faces. Dice are three-dimensional, and as such are polyhedrons.

Since we're only talking about regular polyhedrons (those which have equal-sized faces and angles), you can get through the first ones:

4-sided = tetrahedron
6-sided = cube (or hexahedron, I guess)

In the rest of the cases just replace "GON" with "HEDRON" to get the correct names.

How the heck could you roll a polygon? It's flat, so it would act just like a d2.

I suggest rolling polyhedrons, they're much better at providing a variety of random number ranges. The platonic solids, if memory serves, are tetrahedron (d4), cube/hexahedron (d6), octahedron (d8), dodecahedron (d12), and icosahedron (d20); the d10 isn't platonic but is called, predictably enough, a decahedron.

Perhaps he was thinking outside the dicebag...?

 

[Fast Learner]

the d20 isn't platonic but is called, predictably enough, a decahedron.

He means d10.

 

[CRGreathouse]

He means d10.

Now there's a bad typo -- it totally changes the meaning! I'll edit my post.

 

[Dr_Rictus]

the d10 isn't platonic but is called, predictably enough, a decahedron.

Since you brought it up, we might note that the platonic solids are provably the only possible regular polyhedra. That is, all of their faces and vertex angles are congruent, with all edges equal in length. Which is why you need the irregularly-shaped decahedron if you want to make a d10 with unique faces (as opposed to an icosahedron with 2 instances of each digit on different faces, which is an old-school d10).

As a bit of side trivia, they fall into three distinct classes of rotational symmetry (tetrahedron<->tetrahedron, cube<->octahedron, dodecahedron<->icosahedron) where within each class the number of faces in one shape is the number of vertices in the other. You can swap from one shape from the other by mapping the coordinates of face centers to vertices and vice versa.

NAMES OF THE POLYGONS

9 ENNEAGON

This is also known as a nonagon, btw. Enneagon is considered more "correct," but nonagon is often used because it's easier to say.

 

[Oberton]

Duh, I did make a mistake. I should have remembered we are working with three-dimensional objects...

Sorry...

strange, my orange "icosahedron" prefers to be called Steve.
