The triangle calculator is written in JavaScript and can solve triangles of all shapes and sizes. The software is still in the beta stage of development -- use it at your own risk! The triangle calculator is much faster than solving triangles using an ordinary calculator, and it's great for a quick check of trigonometry homework that involves solving triangles. And, the triangle calculator can solve any plane triangle, not just ones with right angles.
