Arc BAD is called the:
Major arc.
Minor arc.
Both halves are equal so it may be major or minor arc.
None of these.
The length of the arc BAD is greater than that of the arc BCD. Thus, BAD is the major arc of the circle while BCD is the minor arc.
The shaded region consists of a chord and the arcs of the circle. The region in the yellow has the major arc so it is the major segment and the purple region consists of the minor arc so it is the minor segment.
