GEUP is an interactive geometry tool. Lets you dynamically explore Mathematics, build mathematical models of real world or create interactive mathematics presentations. Main features: Capability to apply in Euclidian, analytical, transformational geometry; Capability to construct the basics geometric elements: points, lines, circles, polygons (including regular polygons); Calculate fast and precise loci (including by lines and circles); Enables geometric transformations (symmetry, reflection, translation, dilation, rotation, inversion); Capability to define conics (ellipses, hyperbolas and parabolas); Verify geometric properties (parallel, perpendicular, member, collinear, equidistant); Capability to define, combine, evaluate and plot functions; It works with Cartesian and polar coordinates.
