GNU Dr. Geo, be a Geometer!
Dr. Geo, a software to design & manipulate interactive geometric sketches.
It helps kids to explore geometry.
Distributed with its source code it is modify-me-ready.
Dr. Geo aim is to be an open, easy to study, modify and extend interactive geometry software. It is distributed with its source code you can modify while using it. Ten years old kids use Dr. Geo to explore Euclidean geometric sketch, agile kids extend and program it with its embedded dynamic Smalltalk language and user interface.
Just like other interactive geometry software such as Cabri, Cinderella, Geogebra, Carmetal, with Dr. Geo the user creates a geometric sketch and manipulates it according to its constraints. What sets Dr.Geo apart from the other geometry software is the possibility of studying and even modifying/extending its source code while s/he is using it to create a figure.
Dr Geo is an educational oriented software. It's an observatory to explore geometry situation in an interactive way in opposition to figure drawn on a sheet of paper. The user interface was designed to be simple but efficient for young users. In spirit, Dr Geo is a free education tool for schools where freedom and equality matter.
