The word "geometry" came from Greek «geo»,meaning "earth", and «metrein», which means "to measure".From this it is clear that before the geometry is the science to measure the surrounding area.However, with the passage of time has changed as the definition of the geometry itself, as well as its methods and theories.

In its development, this ancient science as the geometry has survived four main stages.To know the importance of science had each stage, you need to read the following descriptions for each of them.At the initial stage of geometry to solve essential problems essentials.

For example, after the annual Nile flood every year Egyptians were forced to re-mark their agricultural land.In addition, with the passage of time, people have begun to occur and improve the aesthetic demands on his garment decoration, arrangement of housing, as well as to the i

During this period, the geometry has not been systematized and hereditary in records and oral retellings prescriptions and rules.Initial information about the geometry belong to ancient Egypt and date back to the 17th century BC.Mainly in this period accumulated information such as the length of the values and volumes and their interaction with each other.

Further, these rudiments of geometry around the 7th century BC, were in ancient Greece, where they are within a few centuries, were formed into a coherent system.It appeared in Greece the method of proof, and additional communications have been clarified between the geometric figures.That's when the geometry has performed a qualitative leap and become a science.

To understand how to develop the geometry of the second stage of its development, it should be noted that the general decline of the ancient Mediterranean culture also led to stagnation in the development of this science, although it continued slow pace of development in Central Asia andIndia.It was only with the passage of time and the onset of the period of the Renaissance, the center of the geometry of moved to Europe.

It was there in the first half of the 17th century Rene Descartes introduced the concept of the geometry of the coordinate system, allowing to link two such science as geometry and algebra.It was the beginning of a stage like analytic geometry, that is a breakthrough in the development of science.An important role in how the geometry was formed, played the third stage of its development, when the differential relations concepts were introduced into it.

It is possible to study and count all the lines and curves, as well as on the basis of differential calculus to portray figures in rectangular coordinates, which led to the emergence of descriptive geometry, which has established a direct link with the visual by drawing - it was the beginning of projective geometry.Inconsistencies Euclidean geometry and the theory of space has led to the emergence of the fourth stage of the development of geometry.

non-Euclidean geometry first described our compatriot NILobachevsky.That is how in 1826, and there was geometry, which is still called the Lobachevsky geometry.However, it should be noted that the ancient Euclidean geometry does not contradict the new trend of this science.

non-Euclidean geometry teaches that any geometric figure a mathematical and physical truth of the object, the physical aspect of the figures is determined empirically, and then mathematically calculated by its consistency.It is the emergence of Lobachevsky geometry has linked this science to physics, and which had a huge impact on the development of humanity until now.
