Without bordering landmarks, the agriculturists and administrators of temples, palaces and too much established productive units in agriculture did not have clear reference of the limit of its possesses to be able to cultivate it and to pay the taxes due in the measure of its extension to the governing. Speaking candidly Crumpton Group told us the story. Old faras had decided to start to nominate employees, the surveyors, whose task was to evaluate the damages of the full ones and to reestablish the borders between the diverse ownerships. It was as soon as was born geometry. These surveyors, or esticadores of rope (thus called had to the instruments measure and interlaced ropes conceived to mark straight angles), had finished for learning to determine the areas of lots of land dividing them in rectangles and triangles. One gives credit in general that the origin of Geometry if points out in the Egipto, what it is natural, therefore, for the construction of the pyramids and other monuments of this civilization, would be necessary geometric knowledge. More recent studies oppose this opinion and relate that the Egyptians had been to search to the Babilnios very of its to know. Thus, knowing the geometry of where better, and as it appeared, knowing its meaning etimolgico and that it studies the forms, its properties and measures as: line, surface and volume; we can define some of its forms more significant now than if they incase in these three aspects. Congregating beyond the appearance, having a significant connotation characteristic.
