Interactive geometry software combines three branches of mathematics: geometry, calculus and algebra. This type of software allows users to create and modify constructions, which are generally in plane geometry. Construction involves building mathematical shapes out of points, lines, conic sections, hyperbola, ellipses, and circles. These diagrams can then be altered and the effects of the mathematical properties of the shapes can be observed.
Typically geometry software covers a wide range of application areas, including pure Euclidean and non-Euclidean geometry, computer-aided design, and computational kinematics. It is often found being used for learning and teaching mathematics in schools and colleges and for research purposes.
Our gold medal winner is Dr. Geo, great open source software for children of all ages to explore and fall in love with geometry. The user interface is simple and easy to use, essential traits for any good educational software. The software has been in active development since 1996.
All of our medal winners are, of course, released under a freely distributable license and can be downloaded without charge. They are educational oriented software.
