# Construction and geometry

Constructions: 11 basic constructions when we do constructions in geometry, we will use the traditional approach that uses only two instruments, a compass and a straightedge. 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 geometryin 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 history of geometry geometry's origins go back to approximately 3,000 bc in ancient egypt ancient egyptians used an early stage of geometry in several ways, including the surveying of land, construction of pyramids, and astronomy.

Philosophy of constructions constructions using compass and straightedge have a long history in euclidean geometry their use reflects the basic axioms of this system. Line is a basic construction of all fiures in geometry to construct many figures in geometry we join two or more lines we use ruler to construct a straight line.
