GEUP is an interactive, powerful and easy to use software for learning and
doing Geometry on the computer. GEUP allows you to verify geometric properties in a precise way and to discover new properties through the exploration.

With GEUP we can explore mathematics visually and interactively, build
mathematicals models of real world or create interactive mathematics
presentations easily.

Here are some key features of "GEUP":

· Capability to apply in euclidean / non-euclidean(macros), analytical, transformational geometry.
· Capability to construct the basics geometric elements: points, lines, circles, conics, polygons (including regular polygons).
· Optimized for maximizing the calculation and visualization speed.
· It allows to modify geometric elements dynamically, reforming very fast the construction.
· Calculate fast and precise loci (by points, lines and circles).
· Inverse dragging for the points that defines and describes a locus.
· Intersections with loci.
· Locus of locus and locus from a point on a grid.
· Enables geometric transformations (symmetry, reflection, translation, dilation, rotation, inversion).
· Verify geometric properties (parallel, perpendicular, member, collinear, equidistant).
· Capability to define, combine, evaluate and plot functions.
· Capability to define parameters with visual variation and animation.
· It works with cartesian and polar coordinates.
· Capability to plot points through a dialog box.
· Capability to define user construction tools through macros.
· Capability to attach and share macros between documents.
· Construction list.
· Capability to dynamically visualize the euclidean plane and modify its dimensions.
· Automatic selection of points.
· Capability to define animations on the construction.
· Parametric colors.
· The interface adapts to the screen resolution.
· Edit and modify the construction at any time.
· Capability to print any area of the defined plane and change the scale.
· Easy to learn and easy to use.
· Fully customizable. It includes multi-language support.


Requirements:

· Pentium Processor 133MHz (1GHz for Windows Vista or 300 MHz for Windows XP)
· 512 Mb RAM
· 16-bits 65536 colors video card - 640x480
