The earliest recorded beginnings of geometry can be traced back to ancient Mesopotamia and Egypt in the 2nd millennium BC. Early geometry was a collection of empirically discovered principles used for practical applications like surveying, construction, astronomy, and crafts. Some of the earliest known texts on geometry are the Egyptian Rhind Papyrus and Moscow Papyrus from around 2000-1800 BC and 1890 BC respectively, as well as Babylonian clay tablets such as Plimpton 322 from around 1900 BC. These texts contained early formulas for calculating properties of shapes like the volume of a truncated pyramid.
