A point has no dimension D. In fact, it has been said that apart from the Bible , the Elements is the most widely read and studied book in the world. In writing the Elements Euclid collected and extended many of the ideas of other Greek mathematicians before him. The Elements is basically a chain of propositions encompassing most of the geometry, number theory, and geometric algebra of the Greeks up to that time. The definitions of Book I include those of points, lines, planes, angles, circles, triangles, quadrilaterals, and parallel lines. The five postulates may be translated into the following:.

However, some mathematicians have claimed that postulate four can be proven; [6] and many have believed that postulate five, partly because of its length and complexity, can be proven. He claimed that one must postulate that two distinct straight lines cannot have a segment in common. Once again, be prepared to explain this when you present the proposition, but do not include it in your summary. Here begins the actual proof so you have the first step of your summary.

Here Euclid states what the proposition has proven. The steps you would send into me would be the following- repeated steps may be excluded if you like.

### Euclid's Elements

Geometry students will be given an numerical evaluation for their work in the tutorial. There are four levels of performance. No letter grades are given. From memory You cannot miss more than 2 steps 2. Did not have steps prepared In order to guarantee a pass in Geometry, at the end of the year, students must have maintained an average of 2. Whether a student fails or not is ultimately at the discretion of the tutor, however, the numerical system will be held outside of extraordinary circumstances.

If you feel your students is falling behind, it would be good to encourage them to deliver their propositions by memory as often as they can and to volunteer for the large proofs. Please keep a record of your performance on all propositions that you demonstrated so that you can find your semester average. The tutorial is based on the original Element's rather than a summary text.
