- Solutions Depth: The official solutions are masterclasses in logic, not just answers.
What is this book?
Unlike standard textbooks that teach theorems first and then provide drills, this book is a problem-solving workshop. It assumes you already know the basics: similar triangles, cyclic quadrilaterals, Power of a Point, and elementary trigonometry. titu andreescu 106 geometry problems pdf
However, it is worth noting that the formatting of geometry proofs in PDFs can sometimes be tricky due to the reliance on diagrams. The official publications by XYZ Press are lauded for their high-quality typesetting, which ensures the diagrams are clear—a crucial factor when dealing with complex geometric constructions.

- Attempt before peeking – Spend at least 30 minutes on an introductory problem, 1 hour on an advanced problem, and 2+ hours on a hard problem before looking at the solution.
- Keep a geometry journal – Write your own solution in full sentences. Olympiad graders deduct for missing cases (e.g., degenerate configurations).
- Form a study group – Problems #81–106 often have multiple synthetic solutions. Discussing them reveals tricks not in the printed solution.
- Use as a supplement – Pair this with Lemmas in Olympiad Geometry (by Titu Andreescu, Sam Korsky, and Cosmin Pohoata) for theoretical gaps.

Cons
- ❌ Solutions sometimes skip small algebraic steps (assumes strong algebra skills).
- ❌ No separate hint section — you either solve or read the full solution.
- ❌ Some problems require advanced lemmas (e.g., Miquel points, Gauss line) not fully explained upfront.
