Platonic Solid Question (1 Viewer)

[dionb2014]

When I was in year 8 I somehow devised this rule that drew the relationship between sides, vertices and faces or something like that of all of the platonic solids.. Obviously I was not the first person to discover a rule like this and I was wondering what it is if any of you guys and girls no. It's just that today my math teacher said he wanted to tell his year 8 class a rule someone worked out last year.

What the heck is a platonic solid?

 

[dionb2014]

In geometry, a Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex; thus, all its edges are congruent, as are its vertices and angles.

come on?

mate you must be a smart bloke, finding rules and shit in year 8.
it will be interesting to see your atar in 2014

Are you talking about the one which is:

Vertices + faces - edges = 2

I hate anything to do with shapes, surface area or volume xD

My teacher says it will prbably be in one of his powerpoints. I will get back to you guys if I work it out. Thanks for assistance. I don't think it was eulers realisenothing but thanks anyway.

Platonic solids are represented by 2 symbols {p,q} where p = number of edges/vertices on each face and q = number of faces meeting at each vertex.

There is a relationship pF = qV = 2E

Could be that one?

Or Euler's
