Definition:Circle/Arc/Minor

Definition

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

The minor arc joining $a$ and $b$ is the shorter of the two arcs joining $a$ and $b$.

In the above diagram:

the arc $EF$ is the minor arc defined by $E$ and $F$

the arc $BC$ is the minor arc defined by $B$ and $C$.

and so on.
