The figures below depict the various parts of a circle: Minor sector – a sector with a central angle less than 180°.Major sector – a sector with a central angle larger than 180°.Sector: the area of a circle created between two radii.Tangent: a line that intersects the circle at only a single point the rest of the line, except the single point at which it intersects the circle, lies outside of the circle.Secant: a line that passes through the circle at two points it is an extension of a chord that begins and ends outside of the circle.A chord that passes through the center of the circle is a diameter of the circle. Chord: a line segment from one point of a circle to another point.Minor arc: an arc that is less than half the circumference.Major arc: an arc that is greater than half the circumference.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.
More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center.
