A minor arc.
The "Far Arc Near Arc theorem" is used in finding the angle measures of a secant.
A radian measures the degree of the arc. For instance, π radians is 180°. Then, the arc with π radians measures 180°.

Arc AB represents 40/240 = 1/6 of the circumference of the circle. As the angle at the centre subtended by the whole circle is 360° then ∠A0B (if the center is O) measures 1/6 x 360 = 60°. Since a central angle has the same number of degrees as the arc it intercepts, the arc ACB (note we can call the arc AB as arc ACB) measures 60°.

a minor arc measures less than 180 degrees...
An arc that measures exactly 180 degrees is called a semicircle. In a circle, a semicircle is formed when an arc spans half of the circumference, which corresponds to 180 degrees. Semicircles are important in geometry and trigonometry, often used in calculations involving angles and circles.
It is half the circumference of a circle that has an arc of 180 degrees
To calculate the arc length of a sector: calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees) so : (pi * diameter) * (sector angle / 360) = arc length
