Title: Good to augment a textbook
Review: I purchased this book to provide a second source of information for a college senior/ graduate level geometry class. It was quite helpful at times in giving second explanations of topics covered in class at a price significantly less than the class textbook. The book is comprehensive, and reasonably well written for a math book. One drawback was that it does not discuss Poincare's upper half plane model of hyperbolic geometry, only Poincare's disc model is covered. Inversions are well covered, and one could use this information to map from the disc model to the upper half plane model, so this was not a serious omission. I have no regrets about buying this book.
