The first geometrical knowledge was originated from the practical needs of people in ancient times.

People measured distances, made straight spears and arrows, compared their length, etc.

Farming and constructing played a very important role in the development of geometry. People worked out the new rules of comparing figures, calculating some geometrical values and volumes and the rules necessary for the construction of buildings. These rules appeared in Egypt and a bit later in China and India approximately in the 12^th century B.C. In other words the age of geometry is no less than 4 or 5 thousand years

Originally geometry was not a mathematical science though ancient Egyptians knew some facts of geometry such as the volume of a sphere, the Pythagoras theorem and some others. Geometry as a science got its further development in ancient Greece in the 7-5 century B.C.
