A scaled drawing of each calculated shape is shown with a graph paper background in one drawer, while another shows a history of your previous calculations. A definition of each shape and the different ways to perform the calculations is also provided.

Geo-Calc's shapes include an ellipse, rectangle, triangle, trapezium, parallelogram, polygon, prism, cylinder, cone, pyramid and sphere.

Very nicely done -- useful as an educational tool and for harried users as well. Beautiful interface and graphics -- superb info pallette. Those who don't need -- or appreciate the thought, imagination and talent behind this can stick to their slide rules. Well worth the $10 to support great work.

As a registered user of this application I'm quite offended by the review below (if you can call it that). Having to do numerous geometrical calculations at work every day I find this programme very useful and a joy to use - very nice user interface and well thought out. Not that I can't do the calculations myself, but don't we use computers to take the pain out of repetitive stuff like this and speed things up? Unfortunately it's trolls like Lala (LOL) who frequently misuse this review option. Instead of giving a proper review of an application they're just being offensive and destructive.

If you require a special "calculator" to perform these calculation, you should save your money to buy fire woods, since you should not be trusted to use ANY electrical appliance.
