After visiting Geometry Google User Group today, I thought you might be 
interested to visit Geometry Step by Step from the Land of the Incas at:
<http://agutie.homestead.com/>http<http://agutie.homestead.com/>://agutie.homestead.com
 


This website provides an eclectic mix of sound, science, and Incan history 
intended to interest students in Euclidean geometry. Recent additions include 
Simson Line (proof of Simson line), The Raft of the Medusa (problem solving 
with fractals and animation), Archimedes and the Rhombicuboctahedron 
(Archimedes the Geometer), Sierpinski Triangle and Machu Picchu (fractal 
illustration), Johnson's Theorem (three equal circles pass through a common 
point), Varignon and Wittenbauer Paralellograms (quadrilateral: midpoints and 
trisection points of the edges), Van Aubel's Theorem (quadrilateral with 
squares), Langley problem, Butterfly theorem, Sangaku problem, Morley theorem 
and more.

I welcome all of your comments and suggestions.

Best regards,

Antonio Gutierrez
