Sep 14, 2001 · Geometry is the branch of mathematics that studies the shape, size, and position of objects and spaces. Learn about the origins, development, and applications of geometry, from ancient to modern times, and explore its major branches, such as Euclidean, analytic, projective, differential, and non-Euclidean geometry.
Geometry is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space that are related with distance, shape, size, and relative position of figures.
