## What is Geometry?

Geometry is a branch of mathematics that pertains the the location and attributes of a point, line, shape or solid. Geometry is used to find volume, area, and other properties of shapes. Because of these properties, it is a very practical mathematical tool for use in industries such as farming, construction, engineering, and even astronomy.

## A Brief History of Geometry

Because of the practicality of determining volumes and areas, geometry was highly adopted by early cultures. One of the earliest pioneers of geometry was Euclid. Euclidean geometry. Euclid's work in the 3rd century B.C. was followed and utilized for centuries. In addition to Euclid, Archimedes added to the study of geometry by developing new techniques for calculating area and volume. And, if you've every studied geometry, I'm sure you've heard of Pythagoras and the Pythagorean Theorem that explains the calculation of the hypotenuse of a right-triangle.
