Practice your Geometry with free Geometria application
Geometria is the Greek word (and origin) of Geometry, and it is a freeware that provides an interface for creating and solving geometrical problems.
Geometria is packed with a repository of sample figures, problems and solutions classified, according to their complexity, into 4 categories.
You can draw and measure segments and angles, measure areas and volumes, transform, cut and join figures.
Labels and variables provide a convenient abstraction over numeric coordinates and measurements.
Variables are used in calculations and referenced in drawings.
