Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. 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.
The Geometer's Sketchpad is a commercial interactive geometry software program for exploring Euclidean geometry, algebra, calculus, and other areas of mathematics.It was created as part of the NSF-funded Visual Geometry Project led by Eugene Klotz and Doris Schattschneider from 1986 to 1991 at Swarthmore College.

Scratch hardness test or scratch test refers to any of a number of methods of measuring scratch hardness. Resistance to abrasion is less affected by surface variations than indentation methods. Scratch hardness is measured with a sclerometer. [1] Attempting to scratch a surface to test a material is a very old technique. [2]
Fyre is a cross-platform open source tool for producing images based on histograms of iterated chaotic functions; Kalles Fraktaler – Windows based fractal zoomer; Milkdrop – music visualization plugin distributed with Winamp; MojoWorld Generator – a defunct landscape generator for Windows; openPlaG – creates fractals by plotting simple ...
Angle trisection is the construction, using only a straightedge and a compass, of an angle that is one-third of a given arbitrary angle. This is impossible in the general case. For example, the angle 2 π /5 radians (72° = 360°/5) can be trisected, but the angle of π /3 radians (60°) cannot be trisected. [8]
The learning tool was designed by inventor-designer Steve Baer, his wife Holly and others. Rhombicosidodecahedron. The Zometool plastic construction set toy is produced by a privately owned company of the same name, based outside of Longmont, Colorado, and which evolved out of Baer's company ZomeWorks. Its elements consist of small connector ...
Squish is a commercial cross-platform GUI and regression testing tool that can test applications based on a variety of graphical user interface (GUI) technologies (see list below). It is developed and maintained by Froglogic. [1] [2]
