Geometry in the Best of the Web Directory

Geometry

Bob's Pages

An interactive presentation of different geometric figures, including polyhedra, fractals, the arbelos, logarithmic spiral and Soddy's Hexlet.

The Complete Quadrilateral

An interactive column by Alex Bohomolny, discussing theorems and presenting illustrative demonstrations through java-enabled applets.

Diamond Theory

Description of new geometric theory, which reveals that Euclidean symmetry may be invariant under rather interesting groups of noncontinuous (and asymmetric) transformations.

Encyclopedia of Triangle Centers

A compendium of more than 1,000 triangle centers. Also includes links related to triangle centers.

Erich's Packing Center

Illustrated solutions to several covering, packing, and tiling problems. Includes some animated demonstrations.

Geo Doubek

Applet that draws Lissajous Figures.

Geometry and the Imagination in Minneapolis

A collection of handouts during a two-week summer workshop held at the Geometry Center, from June 17-28, 1991.

The Geometry Center

A unified mathematics computing environment supporting math and computer science research, mathematical visualization, software development, application development, video animation production, and K-16 math education.

Geometry Formulas and Facts

Presents a document excerpted from the CRC Standard Mathematical Tables and Formulas (30th edition, 1995). Excerpt does not cover differential geometry.

Geometry in Action

Page collects various areas in which ideas from discrete and computational geometry (meaning mainly low-dimensional Euclidean geometry) meet some real world applications.

The Geometry Junkyard

A collection of geometry materials such as usenet clippings, web pointers, excerpts, papers, abstracts, programs and other materials that are entirely mathematical in nature.

Geometry Page of the Interactive Mathematics Miscellany and Puzzles

Includes various geometry topics, some accompanied by Java-enabled applets, for teachers who want to enliven their web pages or classroom presentation.

The Lepidoptera of the Circles

Uses java-enabled applets to illustrate and prove the butterfly theorem.

The Math Forum: Geometry Research

Serves as a venue for academics to post research announcements, seminars, reviews and abstracts of papers. Also allows for the discussion of academic papers.

Mathematical Curves and Surfaces

A gallery of computer-generated mathematical forms using explicit, parametric, polar, cylindrical or spherical coordinates. Available in French and English.

Mow's Cabri II

Collection of geometry data for Cabri Geometry II.

Native American Geometry

Provides an in-depth look at ancient geometry which originates from a simple circle. Traces the history of the geometry that led to modern cultural symbols.

Packomania

Packings of objects in containers, including circles in a square, circles in a circle, or circles in rectangles. With downloadable source files.

Peek

Program for N-dimensional polytope visualization.

Visual Dictionary of Famous Plane Curves

Provides information, history, illustration of common geometric curves. Also includes methods of classifying curves.

Wallpaper Groups

Provides illustrations and information on different plane symmetry groups.

Wilson's Inversive Geometry

Proving theorems using the Klein viewpoint and some CabriJava illustrations.

Xah Lee's Home Page

Includes a visual dictionary of famous plane curves, illustration of common surfaces, information on discontinuous groups of rotation and translation in the plane, and projective geometry.
