Geometry and Trigonometry

Geometry (means “earth measurement”) is one of the oldest branches of mathematics. It is concerned with properties of space that are related to distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a geometer. The first known application of geometry was surveying in Egypt, where annual flooding of the Nile eradicated the demarcations between fields. Geometry provided the survival tools needed to accurately and efficiently redivide the land into individual holdings after the floods.
