History of Mathematics, very strong on geometry.
A collection of interactive geometry applets. Topics include polyhedra, Poncelet's porism, Soddy's hexlet, Mandelbrot set, Steiner porism, Pappus's chain, Repulsion polyhedra and stereo pictures.
Graffiti is a computer program that makes conjectures in mathematics and chemistry. Links to the conjectures and bibliography.
Features articles about specific problems, illusions, and puzzles. Includes diagrams.
By Clark Kimberling. Over 1000 triangle centres in a searchable compilation with diagrams.
Graphics and links for various packing, tiling and covering problems.
Free online book on geometry in pdf format. Contains material not easily found elsewhere from detailed exposition of elementary absolute geometry based on Hilbert's axioms to more advanced topics.
Information and resources about geometric group theory and low-dimensional topology. People, groups, meetings, links.
Geometry exercises for a two-week summer workshop led by John Conway, Peter Doyle, Jane Gilman and Bill Thurston at the Geometry Center in Minneapolis, June 1991.
Web site for the (now closed) Center for the Computation and Visualization of Geometric Structures at the University of Minnesota. Graphics, multimedia, software, teaching resources.
Excerpts from the 30th Edition of the CRC Standard Mathematical Tables and Formulas (1995), namely, the geometry section minus differential geometry.
Presents problems involving circles and triangles, with proofs, SAT practice quizzes and famous quotes. Also, has examples of geometry in Peruvian culture.
Includes collections from various areas in which ideas from discrete and computational geometry meet real world applications.
Activities of the geometry/topology group at Michigan State University.
A new type of geometric construction that was discovered by Dan Litchfield and David Goldenheim. Includes general explanation and sketch examples.
Offers a variety of resources for teaching and learning about geometry. Problems and theorems are presented with step-by-step solutions for each proof.
Discussion board for geometry professors and instructors to keep informed of the latest research.
Those interested in examining the previous incarnation of the Math Forum may search the archives of the Geometry Forum.
Graphical representations of computer generated forms. (French/English).
A husband and wife from Cornell University have come up with a crafty way to illustrate high-level geometry concepts -- by manipulating yarn into models that help explain the curvature of spaces. The mathematicians talk with NPR's Jacki Lyden about hyperbolic crocheting. [4:47 streaming audio broadcast]
