Geometry from the Land of the Incas Geometry from the Land of the Incas Geometry from the Land of the Incas is a free geometry website funded by advertising, aimed mainly at high school and college age students. Developed by Antonio Gutierrez, the site uses sound, dynamic geometry, animations, science, and Incan history with the goal of raising students' interest in Euclidean geometry. Numerous problems are presented with step-by-step solutions for each proof. Around 2003, the website won several minor awards from educational publications, including One of the Top 10 educational Web Sites Canada's SchoolNet's in 2003 , the Knot #284 Canadian Mathematical Society , NCTM Illuminations
