Let $a$ and $b$ be two points on the circumference of a circle.

The major arc joining $a$ and $b$ is the longer of the two arcs joining $a$ and $b$.

In the above diagram:
 * the arc $ECBDF$ is the major arc defined by $E$ and $F$
 * the arc $CEFDB$ is the major arc defined by $B$ and $C$.

and so on.
