Arc: part of the circumference of a circle.Circumference: the distance around the circle, or the length of a circuit along the circle.It is equal to twice the length of the radius. Diameter: the largest distance between any two points on a circle by this definition, the diameter of the circle will always pass through the center of the circle.It is equal to half the length of the diameter. Radius: the distance between any point on the circle and the center of the circle.Center (or origin): the point within a circle that is equidistant from all other points on the circle.It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. Radius (R)Ī circle, geometrically, is a simple closed shape.
