2. The reason why Euclid was known as the father of geometry because, he was responsible for assembling all the world’s knowledge of flat planes and 3D geometry. http://www.google.com/imgres?q=euclid+the+mathematicia

4.  The elements are made up of 13 volumes dealing with subjects such as plane geometry, proportion, the properties of numbers, incomprehensible magnitudes, and solid geometry.  The work is synthesized by hundreds of years of the teachings of mathematicians.  People credited for these books besides Euclid are, Eudoxus, and Theaeteus.  The Elements were know as the most resourceful texts for a long time.

6.  Euclid was the one to create the postulate!  A postulate is a claim that is put forth and accepted as true.  Euclid’s most famous postulate is the fifth. This is his most well know postulate because it is so complicated and no one has been able to succeed with figuring it out.

7.  A straight line segment can be drawn joining any two points.  Any straight line segment can be extended indefinitely in a straight line.  Given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as center.  All right angles are congruent.

8.  If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough. This postulate is equivalent to what is known as the parallel postulate.
