If you slept through geometry class or you need help with trigonometry studies, this app may be just the tutor you're looking for.
Geometry launches a compact but easy-to-use and functional interface with three small panes. It's a bit plain looking, but looks aren't everything--performance counts a lot with this app. One pane lists the type of calculations (3D area and volume, 2D area, coordinate geometry, right triangle geometry, trig, arcs and sectors), the second lists the shape or theorem or law to be tested, and the third illustrates the item chosen from the second pane. Clicking an option launches a second window with the selected formula and an illustration for entering values and calculating results.
This nifty little app performed very well during our tests. It responded quickly and was very simple to use. It offers a great refresher course and method for checking homework. Practical uses outside of school are obvious for renovators and designers. We especially liked the illustrated calculations and the inclusion of each item's formula. Home-schooling parents who feel weak in mathematical areas will really appreciate this free tool for assisting their students and demonstrating theorems and laws.
