In a standard high school classroom, geometry is often taught as a series of static theorems: "Two triangles are congruent if..." or "The sum of angles in a triangle is..." In contrast, the problems found in Andreescu’s book treat geometry as a dynamic puzzle. The theorems are tools, not definitions. The book forces the student to move from knowing what a theorem says to understanding how and when to apply it creatively.
