12 Pentagons Make a Dodecahedron

Or 2 pentagons each having 6 smaller pentagons in it make a dodecahedron.

Polyhedron like dodecahedron will be explored with Excel to use polygon like pentagon as building blocks.

I have designed and drawn a chain of 12 pentagons to cut and fold to make a dodecahedron dice so we can play with our kids. Excel Trigonometry.
