Geometria
Interactive Geometry Software

Geometria provides a graphic interface for creating and solving problems in solid geometry. It can be used and distributed free of charge.
Geometria is packed with a repository of sample figures, problems and solutions classified, according to their complexity, into 4 categories.
With Geometria, one can draw and measure lines and angles, measure areas and volumes, transform, cut and join figures. Figures can be turned around and rotated as easily as id having them in one's hands.
Labels and variables provide a convenient abstraction over numeric coordinates and measurements. Variables are used in calculations and referenced in drawings.
We are always looking for volunteer contributors. Would you like to translate Geometria into your language?
Problems, solutions and figures created with Geometria versions prior to 3.0 are no longer supported. However, we plan to have all future versions backward compatible.
