Geometry is one of the ancient sciences that has been formed since the early stages of the development of human thought. Its roots go back to deep historical layers. Although geometry developed in different regions of the ancient world, it is clear that its formation began, especially in the countries of the East. The historical development of geometry is characterized by four main stages. However, it is difficult to determine these stages with strict years, because this process was complex and gradual.
