Translated into many languages, this book was in continuous use as the standard university-level text for a quarter-century, until it was revised and enlarged by the author in 1952. World-renowned writer and researcher Nathan Altshiller-Court (1881-1968) was a professor of mathematics at the University of Oklahoma for more than thirty years. His revised introduction to modern geometry offers today's students the benefits of his many years of teaching experience.
The first part of the text stresses construction problems, proceeding to surveys of similitude and homothecy, properties of the triangle and the quadrilateral, and harmonic division. Subsequent chapters explore the geometry of the circle -- including inverse points, orthogonals, coaxals, and the problem of Apollonius and triangle geometry, focusing on Lemoine and Brocard geometry, isogonal lines, Tucker circles, and the orthopole. Numerous exercises of varying degrees of difficulty appear throughout the text.

BEST DOG TOY for TREATS EVER!!!!
Color: Brown
If I could have given more than 5 stars, I would have! I had been giving my 70 lb boxer peanut butter in femur bones that I got at the pet store for years. She loved them but the bones would break down from chewing and biting on them. I would have to throw them away when the edges got sharp in fear of cutting my dog's mouth and tongue. This PETSWEET dog toy was the answer. I have been using yogurt, peanut butter and pumpkin so far. I freeze them with the goodies as is suggested. My dog LOVES her evening treat now and I don't worry about sharp edges hurting her mouth. It is washable so more sanitary than the femur bones.

Great for super chewer.
Color: Red
Update to original review: After leaving initial review the seller reached out and asked how to fix it the issue. I was willing to try same product again. They sent me two and I have had no problems with either of the new ones. Great communication from seller. My dog loves the treat In the center and chews on the product forever. She has not been able to get the top off of either of the new ones. Thanks!

PAY CLOSE ATTENTION TO THE SIZE.
Color: Red
I take full responsibility for not paying closer attention to the size specifications. If you have a smaller breed like a Yorkie, Maltese, or a toy Poodle, this product is perfect for your pup. However, for larger dogs, this is utterly inadequate. It won't entertain them for even 20 seconds, let alone 20 minutes.
