**Childhood:**

Very few little information is obtainable about Euclid but it is assumed that he was born around 330 B.C in Alexandria, Egypt. Going by the accounts of certain Arabic authors, he came from a rich situation. It is said that he was a Greek, born in Alexandria, Egypt and lived in Damascus during his life. Though, there is no convinced support if he was the same person as Euclid of Alexandria is often mystified with Euclid of Megara, a different man who was a philosopher and lived at the time of Plato.

As require of biographical information is slightly abnormal for this time, many researchers judge that Euclid may have not existed at all and, in actuality, his works may have been on paper by a team of mathematicians who took the name Euclid. But this suggestion is again discarded by scholars, citing require of solid evidence.

He studied in Plato’s ancient school in Athens, a position that was only destined for rich people. He got his mathematical training from the students of Plato.

**Career**: Euclid’s ‘Elements book’ is well thought-out as one of the most powerful works in the the past of mathematics, from the time of its journal awaiting the late 19th or early 20th century. It really served as the key textbook for teaching mathematics throughout this time.

He deduced the ideology of ‘Euclidean geometry’ from a little set of axioms in his Elements. Euclid also wrote works on point of view, conic sections, spherical geometry, number theory and rigor.

**The books of elements**

**BOOK -1:**

The first book of elements contains all the basic definitions, postulates, and axioms of various common topics like circle, lines and angles, geometry, polygon etc.

**BOOK – 2** :

The second of elements mainly contained about the propositions and definitions about quadrilaterals, like square and rectangle.

**BOOK – 3 :**

The third book of elements all about the characteristics and features of circles, its radius, diameter, chords etc.

**BOOK – 4 :**

The fourth of elements tells us about the nature of rectilinear and circular figures that when they are inscribed and some time when they are circumscribed.

**BOOK – 5 :**

Ratio is an indication of relative size of two magnitudes. This is what the book 5 of elements is based on. It covers the abstract theory of ratio and proportion.

**BOOK – 6 :**

This book is just the expansion of book 5. It contains the theory and geometric based upon the ratio and proportion.

BOOK – 7 : The book 7 of elements was on of the finest books based on unit And number, part and multiple, even and odd, and prime and relative prime. The basic contraction of book 7 was known as Euclidean algorithm, a kind of reciprocal subtraction.

This book also contained the Euclids divisions lemma which is the easiest way to find a H. C. F of a given couple of number.

**BOOK – 8 :**

The eight book of elements is the advance ment of book 7, telling about the cubic numbers, unitary numbers etc.

**BOOK – 9 :**

The book nine is again an continuation of book eight which fully describes about the multiplication of prime, even, odd no etc.

**BOOK – 10 :**

This book tells us about the rationally and irrationality of straight lines and the figures and ratios formed by them.

**BOOK – 11 :**

The solid figures,angles and planes and similarity are all just in this book.

**BOOK – 12 :**

This book was the the first book giving about the 3d figures, their designs and properties.

**BOOK 13:**

The last book of elements describes about the mean ratio, straight lines high sided polygon’s like hexagon, decagon etc.

**Top 10 Facts you did not know about Euclid**

***The name “Euclid” means “renowned, glorious”.

***His book ‘Elements’ served as the main textbook for teaching mathematics from the time of its publication to until around early 20th century.

***Most of the other Greek mathematicians from Archimedes onward referred to him as “the author of Elements” and not by name.

***Some researchers are of the belief that Euclid was not a historical character and that his works were written by a team of mathematicians who collectively took the name Euclid. However, there is little evidence to support this hypothesis.

***Euclid’s Optics was the first surviving Greek dissertation on the perspective of optics.

***His work ‘Divisions of Figures’ survives only partially in Arabic translation.

***A detailed biography of Euclid was given by Arabian authors though researchers believe the work to be completely fictitious.

***Medieval translators and editors often confused Euclid with the philosopher Eukleides of Megara who lived about a century before.

***The geometrical system he described in the ‘Elements’ is referred to as Euclidean geometry to distinguish it from other so-called non-Euclidean geometries that mathematicians discovered in the 19th century.

***It is often said that ‘Elements’ is one of the most translated, published, and studied of all the books produced in the Western world.
