Indeed , measuring plots of land was one of its first uses. Since those early days thousands of years ago, the subject of geometry has expanded and is used for many things.
People use geometric principles for everything from art to architecture.
We have progressed from simple points and lines to three dimensional figures and beyond. This process was set in motion when a man named Euclid first wrote out the principles of geometry in their now familiar organization and style in his book Elements . So called Euclidean geometry reigned supreme for approximately 1400 or 1500 years. Later it was realized that sometimes in n-spaces of degree 3 or higher, Euclidean geometry did not quite fit the bill. This was the beginning for the ideas of people such as Riemann, Lobachevsky, and Saccheri.
