Titu Andreescu — 106 Geometry Problems (PDF): a vivid tribute to classical problem‑solving

Titu Andreescu’s 106 Geometry Problems reads like a carefully composed playlist for anyone who wants to fall in love with olympiad geometry. This compact collection moves with intention: a short theoretical prelude, then a sequence of problems that climb in flavor and difficulty, each chosen to teach a tactic or reveal a geometric idea. The book’s strengths are surgical clarity, economy of presentation, and a pedagogy shaped by contest experience — problems are not random displays of difficulty but demonstrations of technique. If you have ever dipped your toes into

Final verdict Concise, well‑curated, and practice‑oriented — 106 Geometry Problems is an efficient accelerator for anyone serious about becoming fluent in olympiad geometry. It won’t replace broader theory texts, but as a bridge from routine exercises to contest creativity, it’s superb.

To understand the difficulty curve, consider problem #1 versus problem #106. Problem #1 might be a clean configuration requiring a simple angle chase. By problem #40, you are proving concurrency of three lines you cannot see without drawing three radical axes. Titu Andreescu — 106 Geometry Problems (PDF): a

By problem #80, you are tackling "bottleneck" problems—the kind that take two hours to solve but only three lines to write the solution. Problem #106 is infamous; it is often a modified IMO Shortlist problem requiring an elegant synthetic trick that eludes 99% of contestants.

The rule of this book: If you can solve 80 of these 106 problems without looking at the solutions, you are ready for the national Olympiad team selection camp.
