A geometric shape is a figure that can be defined in terms of its points, lines, angles, and surfaces. Common examples include circle, square, triangle, and rectangle. These shapes can be two-dimensional, existing on a flat surface, or three-dimensional, like cube and sphere, which have depth. Geometric shapes are fundamental in mathematics and are used in various fields, including art, architecture, and engineering. They help in understanding spatial relationships and can be combined or transformed to create more complex designs. Recognizing and analyzing these shapes is essential for problem-solving in geometry.
