  Construction and interactive calculation and visualization
GEUP 9 is an interactive plane geometry software for math visualization and to perform dynamic math calculations. It allows to create dynamic and general constructions/applications visually by defining math elements through the included construction tools. GEUP 9 allows the modification of the construction visually (directly in screen) and it calculates each one of its particular cases in real time. The range of application of GEUP 9 is very wide, next its main applications are described.

Exploring Geometry
The geometric elements defined by its basic tools verify the euclidean geometry axioms and a set of tools at the same level allows its application in analytical, transformational and fractal geometry. Also the capability to define your own construction tools (macros) through the application of the built-in construction tools, allows to create geometry applications about non-euclidean geometries.

Easy to use in Education in all its application areas
GEUP is a great help to teach and learn at any level, helping students to understand concepts more quickly and encourages the exploration and the discovery.

Algebra, Calculus and interactive Mathematics
The capability to define non-geometric elements allows the application of the construction concept in Algebra, Calculus, etc. Use its full potential to create interactive and dynamic math calculations and visualizations and you will discover new ways to study Mathematics in a wide range of areas.

Science and Engineering/Industrial design
The interactive construction, calculation and visualization concept of GEUP 9 implies its application in Physics, Engineering/Industrial design and more to study mathematical models of real world quickly, visually and efficiently. is a component of GEUP and GEUP 3D for 2D/3D CAD modeling.
