Shapes and Ideas // 2012

I was thinking about the dodecahedron and the icosahedron, two platonic solids that are made of twelve pentagons and twenty equilateral triangles, respectively. The Dodeca (twelve) and Icosa (twenty) refer to the number of sides. If you consider the number of vertices on each shape, you find that the numbers are inverted.

So twenty and twelve are really entwined in these solids.
Not to mention that if you combine the two shapes together you get a shape that's made of twenty triangles, and twelve pentagons.
Kind of fun, wonder if anyone here had noticed that.

Best wishes
