Unsolved problems in geometry cover a wide range of topics and questions that have yet to be resolved. Here are a few notable examples: 1. **The Poincaré Conjecture**: While this conjecture was solved by Grigori Perelman in 2003, its implications and related questions about the topology of higher-dimensional manifolds are still active areas of research.
