Cinderella interactive geometry review

Cinderella is very similar to Geometer's Sketchpad. There are some important differences. Cinderella uses more sophisticated algorithms to draw objects and therefore, some minor annoyances of Sketchpad are eliminated. In sketchpad, objects defined as the intersection of two circles may jump from one intersection to another under some conditions. This does not happen in Cinderella. The only shortcoming of Cinderella (in comparison to Sketchpad) is that Cinderella does not do computations. That is, you cannot display the product of two segment lengths. Cinderella works very smoothly, and is half the price of Sketchpad. I like them both, but would go for Cinderella based on price.

Great Geometry on a Computer

I have played around with other software for making geometric constructions, but this is by far the easiest to learn. The basic options are all listed for you at the top of the screen, so that they are easy to access and with a little practice very complex geometric designs can be easily created. Once your design has been created you can grab a point, move it around, and see the effect on other points in the design. The "locus" feature is fantastic for understanding how the motion of one point effects other points in the figure. Your control over point and line, color and size is outstanding. The line clipping function and the ability to make parts disappear while still playing their function makes it possible for you to create designs which demonstrate your ideas in a clear manner. The printed results, with respect to lines and circles, is for the most part outstanding. I congratulate the authors. The price is right. Buy it.
