The Geometer's Sketchpad is a dynamic construction, demonstration, and exploration tool that adds a powerful dimension to the study of mathematics. You and your students can use this software program to build and investigate mathematical models, objects, figures, diagrams, and graphs.
Geometry Expressions is the first geometry software package that allows you to interact with your figure numerically and symbolically. This symbolic interaction brings together geometry and algebra for the first time in an interactive geometry system.
What is GCLC? GCLC (from "Geometry Constructions->LaTeX converter") is a tool for visualizing and teaching geometry, and for producing mathematical illustrations. Its basic purpose is converting descriptions of mathematical objects (written in the GCL language) into digital figures. GCLC provides easy-to-use support for many geometrical constructions, isometric transformations, conics, and parametric curves. The basic idea behind GCLC is that constructions are formal procedures, rather than drawings. Thus, in GCLC, producing mathematical illustrations is based on "describing figures" rather than of "drawing figures". This approach stresses the fact that geometrical constructions are abstract, formal procedures and not figures. A figure can be generated on the basis of abstract description, in the Cartesian model of a plane. These digital figures can be displayed and exported to LaTeX files (or some other format). WinGCLC is the Windows version of GCLC and provides a range of additional functionalities.
