Geometry from the Land
of the Incas
From the website: "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, Nazca Lines, the Quipu , the Lord of
Sipan, Caral: the oldest civilization in the Americas, and more."
Remember making chewing gum wrapper rings? This is a simple
example of the art of knotology, or folding strips of paper into 3D objects.

Native American Geometry
"Native American Geometry is a physical, proportional geometry that originates from the simple
circle. A growing body of architectural and iconographic evidence from Native America suggests it
was a relatively common tradition that has been practiced for at least two thousand years."
Origami and Math
model is both a piece of art and a geometric figure. Just unfold it and take a look! You will see a
complex geometric pattern, even if the model you folded was a simple one." This expansive site
on origami also includes much more for those interested in the art of paper folding.
Paper Models of Polyhedra
"Polyhedra are beautiful 3-D geometrical figures that have fascinated philosophers,
mathematicians and artists for millennia. On this site are more than eighty paper models available
Playing with Symetry
"Try turning your name into something
extraordinary using our symmetry drawing tools. Enter the geometric world of rotations, inversions,
and the art of symmetry."
These fit-all-the-pieces-together games can be challenging!
Rearranging the Furniture
"What is the largest shape that can move
around a hallway corner? Mathematicians have been studying this puzzle since 1966, but they still
don't have the answer. Maybe you can help them out."
