Geometria
Interactive Geometry Software

Geometria provides a graphic interface for creating and solving problems in solid geometry. It is freely used and distributed under GPL.
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 segments and angles, measure areas and volumes, transform, cut and join figures. Figures can be turned around and rotated as easily as if 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.
Try out the new 3.1 release! Among the additions:
  • Switch from one language to another without closing the window.
  • Make font larger or smaller.
  • Comment on solution steps.
  • Rename variables.
  • Drag problem, solution and figure files into the window to open them.
  • Improved menu appearance.
We are always looking for volunteer contributors. Would you like to translate Geometria into your language? Would you like to publish your own problems, solutions and figures in the repository?
