In space, if the arc is part of a great circle (or great ellipse), it is called a great arc. where arc AB is the intercepted arc.. A more formal mathematical definition says that: A circular segment is a region bounded by a chord and the arc of a circle (of less than 180) If it's equal to 180, then it's simply a half circle - semicircle. The arc length is not going to depend only on the measure of the central angle, the arc length is going to depend on the size of the actual circle. (The larger arc is called the Major Arc) Which one is arc of a circle? The angle subtended by an arc at the centre O is called the central angle. In the given circle, AB is the minor arc.
