Dr. Geo is an interactive geometry application that allows users to create and manipulate mathematical constructions. Its graphical environment is designed to help students investigate geometric relationships through experimentation rather than relying exclusively on static diagrams.
Users construct figures from points, lines, circles and other mathematical objects. As the position of a movable point changes, dependent objects are updated automatically, allowing geometric properties and relationships to be examined interactively.
Dr. Geo is particularly suitable for teaching geometry, but it also offers opportunities to explore programming concepts. Its integration with Smalltalk enables users to develop mathematical scripts, extend constructions and investigate numerical methods.
The application is implemented using Cuis-Smalltalk, providing an interactive development environment in which users can inspect and modify the software itself. This combination of geometry and programming distinguishes Dr. Geo from many conventional dynamic geometry applications.
This is free and open source software.
