  ABSTRACT: There have been many books and articles written with the purpose of trying to express an underlying master plan for the major pyramids of the Giza plateau. In this paper, a simple yet accurate geometrical layout, which also includes the Sphinx monument, is demonstrated with the aid of a well-known and widely used computer program. Furthermore, the positions of stars may be added to the same program, enabling the correlation of star positions to pyramids during the time frame of their construction to be determined with accuracy and simplicity.
