Geometria
Interactive Geometry Software

Geometria provides a graphic interface for creating and solving problems in solid geometry. It runs in your web browser. No Internet connection is necessary. Geometria is free software.
With Geometria, one can draw and measure segments and angles, compute areas and volumes, transform, cut and join figures. Figures can be turned around and manipulated as easily as if having them in one's hands.
