Euclid of Alexandria (Greek: Εὐκλείδης) (about 325 BC–265 BC) was a Greek mathematician who lived in Alexandria, Egypt. Little is known about this person, but people think he lived there when Ptolemy I was the pharaoh.
Many people see Euclid as the father of geometry, which is an important part of mathematics. His most popular work is Elements. Many people see the book as history's most successful textbook, that is a book which teaches people. In the book, he starts out from a small set of axioms (that is, a group of things that everyone thinks are true). Euclid then shows the properties of geometric objects and of whole numbers, based on those axioms. He proves new higher ideas are true from these lower ideas. This is the same method as modern mathematics uses. It is called the axiomatic method.
In addition to the Elements, Euclid also wrote works on perspective, conic sections, spherical geometry, and possibly quadric surfaces. Five works of Euclid have survived to the present day.

Data deals with the nature and implications of "given" information in geometrical problems; the subject matter is closely related to the first four books of the Elements.
On Divisions of Figures, which survives only partially in Arabic translation, concerns the division of geometrical figures into two or more equal parts or into parts in given ratios. It is similar to a third century (AD) work by Heron of Alexandria, except Euclid's work characteristically lacks any numerical calculations.
Phaenomena concerns the application of spherical geometry to problems of astronomy.
Optics, the earliest surviving Greek treatise on perspective, contains propositions on the apparent sizes and shapes of objects viewed from different distances and angles.
Catoptrics, which concerns the mathematical theory of mirrors, particularly the images formed in plane and spherical concave mirrors.
All of these works follow the basic logical structure of the Elements, containing definitions and proved propositions.
It is not known where or when he is born. People also do not know why he died.
