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. Later they do sophisticated constructions involving over a dozen steps-and are prompted to form their own generalizations. No measurement of lengths or angles is allowed. Please wait while loading (approx. Constructions - KS4/GCSE geometry teaching resources. The tools to use are a ruler (or straight-edge) and a pair of compasses.
