The circumference A circumference is a closed flat curved where all its points are equidistant from the fixed centre point The flat surface outlined by the circumference is called circle
Elements of a circumference Diameter . All the straight line that go through the centre of the circumference and intersect it at two points Radius . It is the segment that connects the centre of the circumference to any other point Secant . It is a straight line that intersects a circumference at two points Tangent . It is a straight line that crossed the circumference at only the point known as tangent point Arc . It is the fragment of the circumference between any two points Chord . It is the segment that connects any two points of the circumference Diameter Radius Secant Tangent Arc Chord
