GEUP

GEUP is a commercial interactive geometry software program. It lets you dynamically explore mathematics or build mathematical models of real world.

OS: Windows 7/Vista/XP/2003/2000/NT4/Me/98/95

Main features

Capability to apply in euclidean / non-euclidean(macros), analytical, transformational geometry.

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).
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 define user construction tools through macros.
Capability to define animations on the construction.
Parametric colors.
