 Connecting Geometry  Cathleen V. Sanders
A fully credited high school distance learning geometry course offered via the Internet to students throughout the Hawaiian islands as part of a grantfunded pilot project through the Hawaii Department of Education. During this ESchool (electronic school) course Cathi Sanders, a teacher at Punahou School in Honolulu, and her students communicate through a Web page and via email. Chapters include: 1. Communicating in Geometry; 2. Symmetry and Transformations; 3. Theorems in Geometry; 4. Congruent Triangles; 5. Triangle Properties; 6. Right Triangles; 7. Parallel Lines and Planes; 8. Polygons; 9. Similar Triangles; 10. Circles; 11. Perimeter and Area; 12. Surface Areas and Volumes.

 Euclid's Elements  David Joyce; Dept. of Mathematics & Computer Science, Clark University
A version of Euclid's Elements created by David Joyce to rekindle an interest in the Elements and to show how java applets can be used to illustrate geometry and to bring the Elements alive. The text of all 13 Books is complete. Joyce writes: "...deductive logic is learned almost exclusively in geometry... Modern mathematics and science use deductive logic as a primary tool of understanding. In mathematics, especially, nothing is considered to be known until it is proved."

 EUKLID  Roland Mechling
Dynamic geometry shareware in German and English. Create geometrical constructions on the screen just as on paper; then take a point in your drawing and drag it to another place, and the geometrical relations between all of the objects will be preserved.
