famous for the The Lord of Sipan. Right: Butterfly theorem.
Welcome! 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.
