Euclid, who was born in Alexandria in Egypt, lived more than 300 years before Christ. He is renowned to this day for his book ‘Elements’.
For centuries, this book was one of the main texts for teaching geometry. ‘Elements’ is divided into thirteen books, which cover plain geometry, arithmetic and number theory, irrational numbers, and solid geometry.
His books begin with basic definitions, and then go on to prove different mathematical theories. So, it is only natural that Euclid is called the father of geometry. He stressed the importance of logic and reason in teaching and understanding maths. Though some of his books are lost, at least five of them are still in existence, and are proof of his remarkable gift for mathematics.
