"A lucid and masterly survey." -- Mathematics GazetteProfessor Pedoe is widely known as a fine teacher and a fine geometer. His abilities in both areas are clearly evident in this self-contained, well-written, and lucid introduction to the scope and methods of elementary geometry. It covers the geometry usually included in undergraduate courses in mathematics, except for the theory of convex sets. Based on a course given by the author for several years at the University of Minnesota, the main purpose of the book is to increase geometrical, and therefore mathematical, understanding and to help students enjoy geometry.Among the topics discussed: the use of vectors and their products in work on Desargues' and Pappus' theorem and the nine-point circle; circles and coaxal systems; the representation of circles by points in three dimensions; mappings of the Euclidean plane, similitudes, isometries, mappings of the inversive plane, and Moebius transformations; projective geometry of the plane, space, and n dimensions; the projective generation of conics and quadrics; Moebius tetrahedra; the tetrahedral complex; the twisted cubic curve; the cubic surface; oriented circles; and introduction to algebraic geometry.In addition, three appendices deal with Euclidean definitions, postulates, and propositions; the Grassmann-Pluecker coordinates of lines in S3, and the group of circular transformations. Among the outstanding features of this book are its many worked examples and over 500 exercises to test geometrical understanding.Binding Type: Paperback

Virtually indestructible
Size: 8 Inch, Color: Red
Long lasting ball for a large dog. Bought the first one a few years ago. Its been outside all this time, still full of air and was virtually impossible for my large dog to destroy it. The weather affected the surface so ordered a new one. This has outlasted all the other balls.

Great toy for larger dogs
Size: 8 Inch, Color: Pink
This is holding up pretty well with my Great Pyrenees pup. She was able to pull all of the tags off-but the ball is intact for several weeks!

So much fun
Size: 8 Inch, Color: Pink
Best money ever spent hours of fun. We have 3 dogs. They all love to play with this toy. We got the size 3 large is what we ordered. I'm not going to lie I thought it would be bigger when I ordered it. Two of our dogs are large breeds and the other is medium. It's not too big for the medium to play with it. It comes with a ball pump included so convenient. The little tabs are very durable. I can't recommend this enough. This has no squeaking or any sounds. It's nice that you can play with your four legged companion or you can have them play tug or just enjoy pushing the ball around. It is very versatile in play and stimulation.

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days
