Spherical geometry is a branch of mathematics that deals with the study of geometric shapes and properties on the surface of a sphere. This area of research involves the analysis of angles, distances, and relationships between points, lines, and curves on a spherical surface. Spherical geometry is often used in various fields such as astronomy, navigation, and geography, where the Earth's surface is treated as a sphere. It also has applications in computer graphics, robotics, and physics. Researchers in this field explore the unique properties and characteristics of spherical shapes and develop mathematical tools to solve problems related to spherical geometry.
