Introduction to Geometry
Geometry comes from the greek words 'gē metria' meaning 'Land Measurement'. The early Egyptians used geometry to measure the land area of farmlands along the Nile River to preserve the ownership of land whenever the Nile flooded. Geometry was used to construct the ancient pyramids (See image on the Right) from as early as 2640 BC.
