What is "geometry"?

Geometry is the branch of mathematics that deals with the study of shapes, sizes, properties, and the relationships between them. It includes concepts such as points, lines, angles, surfaces, and solids, as well as their measurements and transformations. Geometry is used to analyze and describe the physical world, from simple two-dimensional shapes like triangles and circles to complex three-dimensional structures such as polyhedra and spheres. It plays a crucial role in fields like architecture, engineering, physics, and computer graphics, providing the foundation for understanding relationships in space and solving practical problems.
