A circle is a basic geometric shape consisting of all points in a plane that are at the same distance from a fixed point called the center. This constant distance is known as the radius. Circles are perfectly round and have no corners or edges. They are defined by properties such as circumference, area, and diameter, which is twice the radius. Circles appear frequently in everyday life, for example in wheels, clocks, and plates. In mathematics and physics, circles are used to model rotation, periodic motion, and symmetry. They also serve as a foundation for more complex geometric figures.
