Mathematicians sometimes use the term to encompass higher dimensional geometries with similar properties - see also Euclidean space Euclidean geometry in the plane is called plane geometry . This is the kind of geometry usually taught in high school. Euclidean geometry is named after the Greek mathematician Euclid . Euclid's text Elements is an early systematic treatment of this kind of geometry . Geometry in three dimensions is traditionally called solid geometry In differential geometry, and in constrast to the main types of non-Euclidean geometry it is also called " flat " geometry, or "parabolic" geometry because it is between elliptic geometry which is positively curved, and hyperbolic geometry which is negatively curved. Axiomatic approach The traditional presentation of Euclidean geometry is as an axiomatic system , setting out to prove all the "true statements" as theorem s in geometry from a set of finite number of axiom s.

Next: Spatial Geometry Up: Math 170 Possible Final Previous: Euclid's Geometry Spherical and Non-Euclidean Geometry We have proved in class that there are no similar triangles on the sphere which are not congruent. But this is puzzling! Construct an equilateral triangle on the sphere- and copy the triangle 4 times to form a big triangle, as below: All the small triangles are congruent, equilateral and equiangular. Why doesn't the big one have the same vertex angles as the small ones? Perform this construction on a real ball, using rubber bands to form your lines. (You must turn in the ball.) Tilings. A tiling is a way to cover a space without gaps using identical copies of a single geometrical figure. The equilateral triangle tiles the plane, in a tiling where six triangles meet at each vertex (see below) Find a tiling of the sphere using 20 equilateral triangles where five triangles meet at each vertex. Draw your tiling (using rubber bands for lines) on a real sphere, and turn it in.

What is the historical importance of non-Euclidean geometry? I intend to write in more detail on this topic. For now, here is a brief summary. The development of non-Euclidean geometry caused a profound revolution, not just in mathematics, but in science and philosophy as well. The philosophical importance of non-Euclidean geometry was that it greatly clarified the relationship between mathematics, science and observation. Before hyperbolic geometry was discovered, it was thought to be completely obvious that Euclidean geometry correctly described physical space, and attempts were even made, by Kant and others, to show that this was necessarily true. Gauss was one of the first to understand that the truth or otherwise of Euclidean geometry was a matter to be determined by experiment, and he even went so far as to measure the angles of the triangle formed by three mountain peaks to see whether they added to 180. (Because of experimental error, the result was inconclusive.) Our present-day understanding of models of axioms, relative consistency and so on can all be traced back to this development, as can the separation of mathematics from science. The scientific importance is that it paved the way for Riemannian geometry, which in turn paved the way for Einstein's General Theory of Relativity. After Gauss, it was still reasonable to think that, although Euclidean geometry was not

Children can opt to turn the paper pages and listen to the story read with different voices for each character. Or they can interrupt the read-aloud session to play with the magic pen (permanently attached with a wire). They can point the pen tip to any word on a page and hear it pronounced, or touch a picture and hear a sound effect (such as ''Strike one!'' for the baseball bat). Very similar to the popular Living Books computer games, this 10-by-11-inch book is more portable than a home computer.

CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Non-Euclidean Geometries Introduction Let's solve the following problem: A fellow took a morning stroll. He first walked 10 mi South, then 10 mi West, and then 10 mi North. It so happened that he found himself back at his house door. How can this be? Most people react with disbelief on hearing that the problem has solutions. The four directions (West, North, East, and South) are successively perpendicular to each other. So how can this be? Here's one solution. (The problem has a whole continuum of solutions so that not much will be lost if I give away one of them.) Consider the North Pole. Going 10 mi South from the Pole brings one on a parallel each point of which is located 10 mi South from the North Pole. Walking straight West one stays on the same parallel and, therefore, at the same distance from the Pole. To get there, just stroll 10 mi North. Poles require a special consideration but everywhere else the four directions do form a cross with four right angles. Our solution to the problem shows that there is a triangle with two right angles at the base (which is already strange) and a nonzero angle at the top. There is no escaping it: there is a triangle whose angles sum up to more than 180 o . This is not exactly what we are taught in high school. Every one who took a Geometry class knows that three angles of a triangle sum up to 180 o The high school geometry is Euclidean. Laid down by Euclid in his

Return to my Mathematics pages Go to my home page Non-Euclidean Geometries Are these two lines parallel? It is hard to tell. The line segments are on the same plane, and they do not meet. But, they are just a small part of the entire infinite lines. If you extend the segments to infinity, do they ever intersect? There can be pairs of lines which obviously will intersect, if extended. But, there are also pairs of lines that you can not be sure about. The situation is this: "What happens at infinity is not obvious." There are some things, that happen at infinity, which ARE obvious (more or less). An example is that a straight line just keeps being straight forever. One version of Euclid's Fifth Postulate says: Through a point (P in the diagram) not on a line (l ), one and only one line (l ) can be drawn parallel to the given line. This version is called Playfair's Axiom. While you may believe that postulate to be true, it is not obvious. Other postulates, having nothing to do with parallels, are very obvious. Throughout history, mathematicians were dissatisfied with this overly-complex postulate. They sometimes came up with equivalent postulates. For example, assuming that the sum of the angles of a triangle is 180 degrees (two right angles) is equivalent to the Fifth Postulate. But, no equivalent postulate was much simpler.
