" The degree measure of a minor arc is the measure of the central angle subtended by the arc."
The degree measure of a minor arc of a circle is the measure of its corresponding central angle.
The angle made at the centre of a circle by the radii at the end points of an arc is called the central angle or angle subtended by an arc at the centre.
Look at the figure given below.
Here ACB is the minor arc.
(Degree measure of the arc is equal to the measure of central angle)
