 Parts of a circle A circle is the set of all points in a plane having the same distance from a fixed point. The fixed point is called the center of the circle. The distance between the center of the circle and any point of the circle is called the radius (plural: radii) of the circle. More definitions... An arc of a circle is a portion of the circumference of the circle. AEB is an arc A chord is the straight line which joins the two extremities of an arc. AB is a chord A segment of a circle is a portion of a circle bounded by an arc and its chord. A sector of a circle is a portion of a circle bounded by an arc and two radii drawn to the two extremities of the arc.
