The golden ratio is now used to draw the golden triangle
and the pentagram on the same spreadsheet.


    The Pentagon and The Pentagram
- October 22, 2006 -

A group of 12 connected pentagons make a dodecahedron.
A pattern was designed and drawn on this spreadsheet to cut and fold
to make a dodecahedron dice.
Thus polyhedron like dodecahedron will be explored with Excel
to use polygon like pentagon as building blocks.
