Geometry Expressions is the first geometry software package that allows you to interact with your figure numerically and symbolically. This symbolic interaction brings together geometry and algebra for the first time in an interactive geometry system.
Geometry Expressions is a constraint based geometry system. The benefits of this type of system are:
In Geometry Expressions if you put symbols in as the values of constraints, you get symbolic expressions out for measurements (see above figure). This means:“I am very impressed with Geometry Expressions: dynamic construction and visualization combined with symbolic analysis, all in an easy-to-use graphical user interface. I believe this is precisely the type of intuitive computing that would be well-received by students and a real aid to their understanding of many mathematical topics. ”
