Geometry Expressions is an Interactive Symbolic Geometry System.
Geometric figures can be defined by either Symbolic Constraints or numeric locations. Measurements on your drawing are not only presented numerically, but also expressed symbolically as Mathematical Expressions. All the usual constructions are available but also powerful, new symbolic constraints.
Geometry Expressions can be used as a stand-alone program or in conjunction with your favorite algebra system via MathML input and output.
