The Geodesic DomeDate: 4 Aug 1995 10:41:37 -0400 From: Jackie Scheibel Subject: polygons Question: My 7th grade class would like to know what polygons a geodesic dome is made up of. How many polygons and where are any located? Thank you Date: 4 Aug 1995 12:01:59 -0400 From: Dr. Ken Subject: Re: polygons Hello there! Here's some information I found at the site http://www.lsi.usp.br/usp/rod/bucky/buckminster_fuller.html He says that the Geodesic Dome (also called the Buckyball) is made up of 12 regular pentagons and 20 regular hexagons. Then you can put a point in the middle of each of these faces, and divide the hexagons and pentagons up into triangles. That gives us a total of 6*20 + 5*12 = 180 triangular faces. Note that the faces aren't all equilateral triangles. Anyway, if you really want to find out a lot about them, take a look at that page. -K |
