GoGeometry from the Land of the Incas is an educational
website
that offers a variety of resources for teaching and
learning about geometry. The website mixes dynamic
geometry, animations, colorful illustrations, and Incan
history in order to raise students' interest in
Euclidean geometry. Numerous problems are presented with
step-by-step solutions for each proof.

The website has won several awards from educational
publications, including One of the Top 10 educational
Web Sites of the Canada's SchoolNet, the Knot number 284
of the Canadian Mathematical Society, NCTM Illuminations Web
Byte (National Council of Teacher of Mathematics), and
one of the 30 “Desert Island Theorems” of the book: "The
Changing Shape of Geometry, Celebrating a Century of
Geometry and Geometry Teaching" by 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 present-day Cuzco, Peru.
Machu Picchu was an ancient fortress city of the Incas
at the crest of the Andes Mountains near Cuzco. The
Incas were superb craftsmen and thoughtful
architect-engineers.
