 Geometry:  The study of shapes and measurement.
The word Geometry comes from the Greek word geometria, which means "to measure the earth." Early civilizations, such as the Babylonians and the Egyptians, used geometric concepts in their everyday life to do many things. For example, geometric concepts were used to build structures, such as the pyramids, and to plot square corners of fields. However, it was not until Euclid (365-300 B. C.) organized the study of geometry in his book, Elements, that geometry became a true branch of mathematics.

Geometry begins with the Greek prefix "geo," which means earth. Other words that begin with this same prefix are geography, geothermal, and geology. Why do you think geometry starts with a prefix that means "earth"?

The geometry that we typically are familiar with is Euclidean Geometry, also called Plane Geometry (a study of points, lines, and planes and their interactions).
