The XYZ Mathematical Olympiad and similar high-level competitions require more than rote memorization. They demand creative problem-solving, deep spatial intuition, and a robust toolkit of geometric properties. Among the most revered preparation materials for competitive mathematics is by legendary mathematician and educator Titu Andreescu, along with co-authors Michał Rolinek and Josef Tkadlec.
Even though the book provides diagrams, drawing your own helps in understanding the problem's structure.

Let me be honest:
If you don't know the difference between the orthocenter and the circumcenter, or if you cannot prove that the angle between a chord and a tangent equals the angle in the alternate segment, put this book down and grab "Geometry Revisited" by Coxeter first. Even though the book provides diagrams, drawing your

The book is highly acclaimed within the competitive mathematics community. Key points of praise include: mentioned here, such as Inversion or Barycentric coordinates
Do not attempt this if you are not comfortable with cyclic quadrilaterals, spiral similarities, and barycentric coordinates. Start with a gentler text. But if you are ready to bleed (figuratively) over a geometry proof, this PDF is your crucible.
What makes the search for the truly worthwhile is the emotional payoff. Geometry is unique among math contest subjects because the solution—once seen—seems inevitable. You will spend three hours staring at a tangled mess of lines, feel defeated, peek at the first line of the solution ("Reflect point P across the median..."), and suddenly the entire figure collapses into symmetry.
