Mathematical figures are shapes or forms that can be defined and analyzed using mathematical concepts. Common examples include triangles, squares, circles, and rectangles. These figures can be two-dimensional, existing on a flat plane, or three-dimensional, like cubes and spheres. Each figure has specific properties, such as angles, sides, and symmetry, which help in understanding their characteristics. Mathematical figures are essential in various fields, including geometry, trigonometry, and calculus. They serve as the foundation for solving problems related to space, measurement, and design. By studying these figures, mathematicians and students can develop skills in reasoning and critical thinking, which are applicable in real-world situations.
