Within each topic, the problems are arranged in approximate order of difficulty. Detailed solutions (as well as hints) are provided for all problems, and specific answers for most.Invaluable as a supplement to a basic geometry textbook, this volume offers both further explorations on specific topics and practice in developing problem-solving techniques. Review: Intuitive Guide - This book is suitable for anyone who want to learn advanced high school geometry or want to participate in any mathematical contest and have to learn much though not really new on it. The problems are set from the quite easy to advanced, with many of them are quite simple so you don't get frustrated because you can't do any of the problems. It covers the basic and common problems in math contest. Unfortunately, it don't have good set of theorems. Sure, it's written on the back but they're not easy to navigate. Also, many of them are not really basic even for contest geometry. Like its title, 'Challenging' is sure quite challenging, since many of the problems, though not really hard, need deeper thinking and you need to draw the 'help line' to solve the problem. The hints written on the back is not really helpful. Overall, for those who want to improve skills, participate in contest, or teacher who wants to make a surprise test, this book is a really good source of information. Review: Fun fun fun - It's late at night, hard day's night :) The girl is sleeping already, the dogs snoring quietly in the kitchen, I'm about to go to sleep. But before that - just one look in this book, just one problem to fall asleep with. Ah, hour an a half later when the problem is solved I really off to bed :) It's such a fun book. Some of the problems are unimaginary hard. Some are easier. All of them are enjoyable, challenging and satisfying. For whom who loves geometry and loves to play with proofs and theorems - You will love it. ## Features - Used Book in Good Condition ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #228,581 in Books ( See Top 100 in Books ) #30 in Geometry #98 in Geometry & Topology (Books) #187 in Algebra | | Customer Reviews | 4.4 out of 5 stars 123 Reviews | ## Images ![Challenging Problems in Geometry (Dover Books on Mathematics) - Image 1](https://m.media-amazon.com/images/I/718bnryTLzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Intuitive Guide *by P***K on September 2, 2010* This book is suitable for anyone who want to learn advanced high school geometry or want to participate in any mathematical contest and have to learn much though not really new on it.

But before that - just one look in this book, just one problem to fall asleep with. Ah, hour an a half later when the problem is solved I really off to bed :) It's such a fun book.

For whom who loves geometry and loves to play with proofs and theorems - You will love it. ### ⭐⭐⭐⭐ Problems and solutions *by J***S on October 29, 2007* Posamentiers' book is a little bit unbalanced. It contains around 200 problems with solutions. The easy problems are just what you would expect in the exercises sections of an introduction to Euclidean geometry like Kiselev's Geometry / Book I. Planimetry . The the harder problems you will find as classical theorems and examples in more advanced texts like Altshiller Courts' College Geometry: An Introduction to the Modern Geometry of the Triangle and the Circle (Dover Books on Mathematics) . A more balanced text would have contained more intermediate problems and the harder ones would have been more "original". The methods used are purely synthetic, no analytic geometry. The book is aimed at an advanced high school level audience. Prerequisite is the stuff you find in a book like kiselev I mentioned above. If you need a book to train your geometric problem solving abilities I think that Altshiller Courts' book is a better choice although there are no solutions to the exercises in that book. But what use are the solutions? Problems should be solved and not looked up! For many problems, especially the hard ones, several solutions are provided. To me this is what makes the book attractive. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/8814341-challenging-problems-in-geometry-dover-books-on-mathematics](https://www.desertcart.hu/products/8814341-challenging-problems-in-geometry-dover-books-on-mathematics) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-05-24*
