With Geometry Helper you can get help with five (for now!) geometrical shapes: triangle, circle, square, pentagon and hexagon. You will have to input one angle, the radius, the side, the area or the diagonal, and you will be given the other properties of the shape. Any comments are welcomed here or through email@example.com
Change log, V1.2:
- New shapes: Pentagon, Hexagon
- 'Show me the formulas' button in every shape. You can see how the calculations are made.
