106 Geometry Problems from the AwesomeMath Summer Program Authors: Titu Andreescu, Vlad Zarkh Publisher: XYZ Press / AwesomeMath (2013) Target Audience: High school students preparing for Olympiad-level geometry (AMC 12, AIME, USAMO, IMO)

High school students preparing for AIME, USAMO, or international competitions, and ambitious middle school students. How to Practice:

In standard curricula, radical axes are a footnote. In Andreescu’s world, they are a hammer. Problem #47, for example, requires proving concurrency of three radical axes—a classic IMO trap. By the time you finish the 106, you will see radical axes in your sleep.

One common critique of Andreescu’s books is that the solutions can be very dense ("Here is the construction, QED"). If you want a book that teaches you how to think, this is the gold standard.

The book assumes a strong foundational knowledge. If you do not already know your way around Ceva’s Theorem, Menelaus's Theorem, cyclic quadrilaterals, and power of a point, you will hit a wall immediately.

Mastering Geometry: A Deep Dive into Titu Andreescu’s "106 Geometry Problems" and Finding a Better Approach

If you are looking to truly master competition geometry, this book—paired with active, thoughtful study—is an unparalleled resource.

Having a physical copy or a high-quality authorized digital version allows you to annotate, sketch, and engage with the material more deeply. A Better Strategy for Mastery

Titu Andreescu is a well-known mathematician and educator with a passion for geometry. He has written several books on mathematics, including "106 Geometry Problems," which has become a classic in the field. Andreescu's expertise and teaching experience have made him a respected figure in the mathematical community.

: The book is divided into "Introductory" and "Advanced" problem sets. The introductory problems are non-trivial and suitable for AMC/AIME preparation, while the advanced sections reach the level of the International Mathematical Olympiad (IMO).
