You may as well admit that although you appreciate the beauty of the small snub icosicosidodecahedron, you aren't as clear as you might be on the theory behind it. This site can help; here you can view over 850 polyhedra (three dimensional objects bounded by polygons) in VRML format (there are several VRML plug-ins available for the major browsers, and instructions are provided on the site)....

This resource, provided by Professor David Joyce of Clark University, is an excellent examples of how Java can be used to explain basic principles of geometry and trigonometry. A Short Course in Trigonometry is divided into thirteen sections, accompanied by instructive Java applets and selected answered exercises. Professor Joyce shows a wonderful ability to simplify complex concepts and demystify...

Math resources for both students and teachers are given on this site, spanning the general topics of arithmetic, logic, algebra, calculus, complex numbers, and Euclidean geometry. Lessons and how-tos with clear descriptions of many important concepts provide a good foundation for high school and college level mathematics. There are sample problems that can help students prepare for exams, or...

10Ticks is a montage of free mathematics lessons, worksheets, and games based on the UK's National Numeracy Strategy. One of the most popular attractions of the Web site is Pac Math, a fun game that allows children to practice basic arithmetic. Over 200 worksheets discuss topics in algebra, geometrical shapes and spaces, statistics, and more. Several more features are available after registration....

This metasite "collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications," according to the site's provider, Dr. David Eppstein of the University of California at Irvine. Categories available include Geometric References and Techniques, Design and Manufacturing, Graphics and Visualization,...

The University of Minnesota Geometry Center is a mathematics research and education center that supports math and computer science research, mathematical visualization, software development, application development, video animation production, and K-16 math education. The website describes some of their projects that use technology to visualize and communicate mathematics and related sciences....

Science UTM offers online articles and activities "for people who like science." Science U and the web-design and development company that owns and operates the website, Geometry Technologies, were formed as a result of the closure of The Geometry Center at the University of Minnesota. One of the conditions of that grant, which funded The Geometry Center and ended in 1998, was that the Center...

Basic geometry resources are always in demand, and educators and students alike will breathe an easy sigh of relief as they are introduced to this set of resources dedicated to this ancient branch of mathematics. Provided by Eric Weisstein at Wolfram Research, the site is simple to navigate and is divided into subtopics that include coordinate geometry, dissection, distance, line geometry, and...

To some the word Illuminations may bring to mind Walter Benjaminâ€™s classic work, and still others may imagine those manuscripts that were a product of the medieval intellect and imagination. In this case, the illuminations in question are a set of mathematical teaching and learning tools designed by the National Council of Teachers of Mathematics. Their website was redesigned in early 2006, and is...

Developed by Dr. Abdelkader Dendane, a lecturer at the United Arab Emirates University, the Analyze Math website is designed to provide curious minds with access to in-depth tutorials on such topics as logarithmic functions, systems of linear equations, and calculus. The site also covers materials from the fields of trigonometry and the sometimes vexing field of statistics. Utilizing Java applets,...
