Unsolved Problems in Intuitive Geometry

Unsolved Problems in Intuitive Geometry presents a collection of geometric problems and conjectures that remain unresolved. The book compiles mathematical challenges from the field of discrete and computational geometry that can be understood through intuitive visualization. Each chapter focuses on specific problem areas like circle packings, polygon decompositions, and point configurations in the plane. The text provides background context and explains prior attempts at solving these problems while highlighting where gaps in mathematical understanding remain. The problems are illustrated through clear diagrams and examples that make complex geometric concepts accessible. Technical proofs and formulas are balanced with plain language descriptions of the core mathematical ideas. This work exemplifies how seemingly simple geometric questions can lead to deep mathematical investigations that persist across decades. The book serves as both a reference for researchers and an invitation to explore foundational questions in geometry that continue to resist solution.
