CIRCLE AND CIRCLE

Circle and circle are considered to be one of the most important and widely used concepts in geometry. A circle is a set of points equidistant from a given point in a plane, while a circle is a geometric figure bounded by a circle and its interior. Through these concepts, basic geometric elements such as radius, diameter, center, tangent, arc, and sector are studied. Formulas for calculating the area and length of a circle and circle are widely used not only in theoretical issues, but also in practical fields - physics, engineering, architecture, and technology. This article covers the definition of a circle and circle, their main elements, properties, formulas for calculating the area and length, and their practical significance. The article serves to develop geometric thinking in students.
