Euclid Of Alexandria may be the best-known mathematician of the world, he is best known for his work on mathematics The Elements. The fact that his work has survived so long, 2000 years in fact, is a tribute to his mathematical genius, however very little of him is known. Three theories abound as to the true nature of this historical figure. Not all historians agree that Euclid was in fact a historical figure, some argue that the school in Alexandria took up the name Euclid to publish their works. But the more accepted theories are that Euclid was in fact a real historical figure who may have been the leader of a team of mathematicians. In Euclid’s first postulate he states that it is possible to draw a straight line from any point to any point. The first postulate gives meaning to the term “point.” For example, any two points such as A and B, there is a line AB that has them as endpoints. In Euclid’s second postulate, it is assumed that it is possible to produce a finite straight line continuously in a straight line. In the third postulate, Euclid states that a circle may be drawn with any center and distant (that is radius.) A compass, for example, demonstrates this postulate. When one draws a circle using a compass, one is plotting all the points a certain distance ‘r’ from the center point. In the next postulate, all right angles are equal to one another. In the last postulate, it states that through a given point not on a given line exactly one line can be drawn paralle...
