Generation

Spherical geometry is the study of shapes and angles on the surface of a sphere, where the "straight lines" are actually great circles (like the equator or lines of longitude). Unlike flat Euclidean geometry, the angles of a triangle always sum to *more* than 180°, and parallel lines don't exist—any two great circles must eventually intersect. This geometry isn't just theoretical: it's essential for navigation and GPS, since Earth's surface is (approximately) spherical, so the shortest path between two cities is along a great circle, not what appears "straight" on a flat map.
