Geometria is an interactive application for creating and solving problems in solid geometry. It allows users to construct, manipulate and examine three-dimensional figures through a graphical interface running in a web browser.
The software is primarily designed for mathematics education. Teachers can create geometry problems, specify expected answers and share exercises with students. Students can then work through the problems by manipulating figures, making measurements and performing geometric constructions.
Geometria supports operations on convex polyhedra, including measuring angles and distances, calculating areas and volumes, and transforming figures. Its interactive viewing controls make it easier to examine objects from different perspectives and understand spatial relationships.
This is free and open source software.
