It is one of the most basic research contents in mathematics, which has the same important position as analysis and algebra, and has a very close relationship. Geometry has a long history and rich contents. It is closely related to algebra, analysis and number theory.
As a mathematical concept, geometry refers to geometric figures, points, lines, angles, surfaces, shapes or plane figures composed of them. Geometry is a finite part of a space surrounded by planes and surfaces. Such as cube, cuboid, prism, cylinder, cone, sphere, ellipsoid, etc.
geometrical characteristic
1, geometry confirms many algebraic problems and expands the breadth and depth of mathematics; It is also a bridge for the practical application of mathematics in life and production, which has important exploration significance.
2. Geometry has a long history and numerous academic achievements in China and the West. Such as Pythagorean Theorem, Pythagorean Theorem, Euclid Geometry, Zu Chongzhi's Pi and so on. Geometry is a branch of mathematics parallel to algebra, and it is also the basis of "number shape".
