The official PDF version is “better” than scanned or bootleg copies:
| Book | Strength | Weakness vs. 106 Geometry Problems PDF | |-------|----------|---------------------------------------------| | Lemmas in Olympiad Geometry | Rich theory | Fewer solved examples | | EGMO (Euclidean Geometry in Mathematical Olympiads) | Comprehensive | Less focused on problem sets | | 106 Geometry Problems | Balanced theory + problems + full solutions | Shorter than EGMO, but better for practice drills | titu andreescu 106 geometry problems pdf better
