TrigSolv

TrigSolv is a geometry solving application designed with students, teachers, engineers, and architects in mind. It will solve all of the main geometric figures including triangles, trapezoids, parallelograms, rectangles, ellipses, and circles. Simply enter the measures of the shape that you know and TrigSolv will find the rest for you. Once the figure is solved, TrigSolv will show you an exact scale drawing of it.
