Geogebra is the best online geometry software for creating different geometric figures - points, lines, angles, triangles, polygons, circles, elipses, 3D planes, pyramids, cones, spheres.

Then, you can measure the angles and midpoints of the shapes to solve or create. Can be used for calculating values of a triangle, a right-angled triangle, circle, pie slice, segments of circles, squares, cylinders, cones, truncated cones, sphere and rectangular The Geometer's Sketchpad offers five different tools to create geometric shapes to help you visualize math problems. Based on the values of the geometric shape it can calculate the unknown one. After some construction is done, one can move the points one started with and see how the construction changes The program is used for geometric calculations. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines, circles or other points. Of course the author makes no guarantees about the program, but you will probably find it to be quite useful Interactive geometry software or dynamic geometry environments are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. Selection Groups-group a bunch of objects, then select them later with two clicks.Īn installation of Trolltech's Qt 3.3.x framework (a download bookmark is included with the installer).What is Geometer? Geometer is a free dynamic geometry program that runs on Macintosh or Windows and allows you to draw and modify euclidean geometry figures. View panning/zooming and multiple simultaneous viewsĮxport view to image file, including antialiased option Pretty formulas for calculations-with my libkformula Transformations (rotation, translation, scaling, reflection)Ĭonstruction of adaptively sampled loci for better quality and speedĪbility to easily redefine points to 'edit' drawingsĮasy to use editable scripting/macro with support for recursion

KSEG was inspired by the Geometer's Sketchpad, but it goes beyond the functionality that Sketchpad provides.įast core which can support large constructionsįree/GPL-runs on Linux (and probably most other systems which support Qt)Ĭonstruction of points, segments, rays, lines, circles, and arcs Despite the name, it is Qt based and does not require KDE to run.

I can usually make a construction in KSEG in less than half the time it takes me to do it with similar programs. It is very fast, stable, and the UI has been designed for efficiency and consistency. KSEG can be used in the classroom, for personal exploration of geometry, or for making high-quality figures for LaTeX. Of course, you can do a lot more than that-see the feature list below. You create a construction, such as a triangle with a circumcenter, and then, as you drag verteces of the triangle, you can see the circumcenter moving in real time. KSEG is a Free (GPL) interactive geometry program for exploring Euclidean geometry.
