Hyperbolic geometry is a non-Euclidean system with a constant negative curvature, leading to infinite parallel lines and triangles with angles summing to less than 180 degrees. It challenges Euclidean geometry's parallel postulate and has applications in relativity, network design, and art. Pioneered by Gauss, Lobachevsky, and Bolyai, it represents a significant shift in mathematical paradigms and enriches our understanding of spatial relationships.
