Euclid was born some time around 300 B.C. He was a very famous Greek mathematician often known as Euclid of Alexandria, or as "Father of Geometry." The name Euclid in Greek means "Good Glory." He created the principles of what is now called Euclidean geometry. He also wrote many works on perspective, conic sections, spherical geometry, number theory, and rigor. Euclid once said that "there is no royal road to learning geometry. This means that there are no shortcuts when it comes to geometry. |

He published many books, but his most famous book was "Elements." It was mostly known for its geometric results. Although, it also includes the number theory, the connection between perfect numbers and Mersenne primes, the infinitude of prime numbers, Euclid's lemma on factorization, and the way to find the greatest common divisor of two numbers. The geometrical system in the "Elements" was thought to be the only type of geometry possible and was known just simply as geometry. However, now it is referred to as Euclidean geometry to separate it from the other types that were discovered in the 19th century. He wrote many other books. One of them showed how to construct a dodecahedron using cubes
