Question

Which among the following is the major arc?



To be noted: the arc names follow the clockwise pattern.

• A. $AC$
• B. $CB$
• C. $BD$
• D. $AD$

Answer 1

The correct option is D $AD$

The angle subtended at the center is $90$ degree for all the $4$ arcs hence the arcs $AC,CB,BD$ and $DA$ are equal.

However for the arc $AD$; the angle subtended by the arms is $90+90+90=270$ degree at the center.





So, it forms the major arc.

Option (d.) is correct.
