Geometry Expressions is the world's first Interactive Symbolic GeometrySystem. This means: Geometricfigures can be defined by either SymbolicConstraints or numeric locations. Measurements on your drawing are not onlypresented numerically, but also expressed symbolically as MathematicalExpressions.Your drawing comes to life via parametric, symbolic animation.All the usual constructions are available but also powerful, new symbolicconstraints. Geometry Expressions can be used as a stand-alone program or inconjunction with your favorite algebra system via MathML input and output.Think of Geometry Expressions as a geometry front end for your algebrasystem. Or think of it as an algebraic extension of your geometry system.Or think of it as a stand alone system that puts the mathematics back ingeometry.
