Geometry from the Land of the Incas. Math from the 1st grade through Algebra and Geometry. 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 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
architect-engineers.

*Block Perimeter Applet*is an excellent tool for building students knowledge of perimeters. Have them drag boxes from the left inside the simulation window to the green screen. After a number of boxes have been placed on the green screen count the edges of each box that are not touching another box. The number of free edges that you count is the perimeter. - Geometry Circles

- Geometry Diamond Theory: Symmetry in Binary Spaces Symmetry is often
described as invariance under a group of transformations.
An unspoken assumption about symmetry in Euclidean 3-space
is that the transformations involved are continuous.Diamond theory
rejects this assumption, and in so doing reveals that
Euclidean symmetry may
*itself*be invariant under rather interesting groups of*non*continuous (and*a*symmetric) transformations. - Geometry Euclid's Elements, Introduction Euclid's
*Elements*form one of the most beautiful and influential works of science in the history of humankind. Its beauty lies in its logical development of geometry and other branches of mathematics. It has influenced all branches of science but none so much as mathematics and the exact sciences. The*Elements*have been studied 24 centuries in many languages starting, of course, in the original Greek, then in Arabic, Latin, and many modern languages. - Geometry Formulas and Facts The present excerpt covers the area of Geometry (minus differential geometry). It was written by Silvio Levy and is reproduced here with permission. All the figures were made by the author using Mathematica, except those in Section 2.4, which were made using kali.

- Geometry Golenor's Geometry Gala Home Welcome to Golenor's Geometry
Gala! What is contained is an assortment ofdemonstrations that will help
students understand some of the most importantconcepts and theorems of
Geometry. To become good Geometric detectives we need to develop our
intuitive and observational skills. Hopefully you will find each of these demonstrations
interesting and helpful in furthering your Geometric abilities. Even though all of the
demonstrations are based on strict Laws of Geometry, they are
**NOT**rigorous Geometric proofs. - Geometry High School Projects Geometry and its Applications (GeoMAP) is an exciting National Science Foundation project to introduce new discoveries and real-world applications of geometry to high school students. The materials are flexible enough to be used in almost any class from algebra and geometry through precalculus, and are ideal for discrete mathematics or college preservice classes.
- Geometry in Action This page collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications. It contains brief descriptions of those applications and the geometric questions arising from them, as well as pointers to web pages on the applications themselves and on their geometric connections. This is largely organized by application but some major general techniques are also listed as topics. Suggestions for other applications and pointers are welcome.
- Geometry Junkyard These pages contain usenet clippings, web pointers, lecture notes, research excerpts, papers, abstracts, programs, problems, and other stuff related to discrete and computational geometry. Some of it is quite serious, but I hope much of it is also entertaining. The main criteria for adding something here are that it be geometrical (obviously) and that it not fit into my other geometry page, Geometry in Action, which is more devoted to applications and less to pure math. I also have another page on non-geometrical recreational math.

- Geometry Wallpaper Groups Some of these pages are quite technical. You might like to look at the first section on transformations of the plane, then skip to the section on the 17 plane symmetry groups to get an idea of the different kinds of patterns. The sections on lattices, on transformation groups and symmetry, and on history are more technical and, perhaps, most appropriate for college-level readers.
