Geometry Step-by-Step from the Land of the
Incas provides an eclectic mix of sound, science, and Incan history in
order to raise students' interest in Euclidean geometry. Visitors will
find geometry problems, proofs, quizzes, puzzles, quotations, visual
displays, "scientific speculation", Cuzco, Machu Picchu, Lost City of
the Incas, Nazca Lines, the Quipu, the Lord of Sipan, Caral: the oldest
civilization in the Americas, and more. On July 7th, 2007, Machu Picchu
was voted as one of New Open World Corporation's New Seven Wonders of
the World. Site created and maintained by Antonio Gutierrez.
