50 videos • 690 views • by AMS Math Geometry is a branch of mathematics that deals with the study of spatial relationships, including points, lines, angles, planes, and figures. It is a broad field that includes a wide range of topics, including geometry of two-dimensional and three-dimensional shapes, trigonometry, calculus, and topology. Shapes are fundamental objects in geometry that can be defined as a set of points in space that are bounded by a boundary. Some examples of shapes include circles, triangles, rectangles, squares, cubes, spheres, cones, and cylinders. Shapes can be classified based on various properties such as the number of sides, the angles between the sides, the presence or absence of symmetry, and the dimensions. Some of the key concepts in geometry include: Points: Points are the most basic objects in geometry and represent a location in space. Lines: Lines are one-dimensional objects that extend infinitely in both directions. Angles: Angles are formed when two lines or rays intersect, and they measure the amount of turn between them. Polygons: Polygons are two-dimensional shapes with straight sides, and they can be classified based on the number of sides they have. Circles: Circles are two-dimensional shapes with a curved boundary that is equidistant from a central point. Three-dimensional shapes: Three-dimensional shapes, such as spheres, cubes, and cylinders, have length, width, and height and are often used to represent real-world objects. Geometry is a fascinating subject that has practical applications in many fields, including architecture, engineering, computer graphics, and physics.
