Go Geometry from the Land of
the Incas Table of Content

GoGeometry from the Land of the Incas is an educational
website developed and maintained by Antonio Gutierrez,
that offers a variety of resources for teaching and
learning about geometry. The website mixes dynamic
geometry, animations, science, and Incan history in
order to raise students' interest in Euclidean geometry.
Numerous problems are presented with stepbystep
solutions for each proof. All the steps are colorful and
animated.
The website has won several awards from educational
publications, including One of the Top 10 educational
Web Sites Canada's SchoolNet's, the Knot number 284
Canadian Mathematical Society, NCTM Illuminations Web
Byte (National Council of Teacher of Mathematics), and
one of 30 “Desert Island Theorems” of the book: "The
Changing Shape of Geometry, Celebrating a Century of
Geometry and Geometry Teaching", the Mathematical
Association UK, Cambridge University Press.
The Incas built a notable civilization in western South
America in the fifteenth and sixteenth centuries. The
center of their empire was in presentday Cuzco, Peru.
Machu Picchu is an ancient fortress city of the Incas in
the Andes Mountains near Cuzco. Built on the steep
slopes at the crest of the Andes Mountains, with
terraced scientific and agricultural areas, Machu Picchu
features wonderful, almost jointless stonework. The
Incas were superb craftsmen and thoughtful
architectengineers.
