Quick Start Support

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.

Geometria is packed with a repository of sample problems and their solutions classified, according to their complexity, into 4 categories.

Labels and variables conveniently shield the user from numeric coordinates and measurements. Variables are used in calculations and referenced in drawings.

Geometria and its DOS/Windows precursor Polyhedron are based on the carpenter shop approach.
