Geometric constructions are essential in the production of Technical Drawings which are precise, abstract representations of things. This lesson is part of a set of lessons in which students involved in a CAD based Technical Drawing course, would use both CAD and GSP skills to produce and revise mathematical concepts when producing geometrical constructions. The CAD base drawings are real world applications of the geometrical concepts learned.
