- Historic Period: Around 3,000 BCE – Ancient Babylon
While Geometry is technically part of math, it was technically not developed to be part of other forms of arithmetic at the time. It is one of the two fields from pre-modern mathematics though. The earliest use of geometry on record goes back to around 3,000 BCE in ancient Babylon. Geometry was mostly used for astronomy, construction, and surveying for various things. Yet, once Algebra and eventually Calculus came around, geometry truly exploded in its use and abilities. While we mostly knew geometry to be the understanding of properties of shapes and their relationship, it has become so much more.
