Math Illustrations will make calculations in the geometry based on any constraints or constructions you have specified, or just from the sketch. Calculations are output only in Real terms. If you are interested in Symbolic manipulations check out Geometry Expressions. You can download a demo at: www.GeometryExpressions.com.
If you haven't supplied all of the necessary input constraints for an exact answer, the system bases the output value on the sketch.
The table below lists all the available calculations and geometry elements which must be preselected. Be careful when selecting geometry objects, if extra things are selected that are not related to the calculation (like other calculations) the calculations will remain inactive. This can happen by mistake, especially when using the selection rectangle.
