Answer:
The arc of line AB on both sides is a semi circle.
Step-by-step explanation:
A semicircle can be referred to as a one-dimensional locus of points through which half of a circle is formed.
The total angle in a circle is 360°
So, the angle in a semi circle is ½ * 360 = 180°
From the attached diagram, it can be observed that line AB divides the circle into two equal parts; i.e. 180° apiece
Hence, the arc of line AB on both sides is a semi circle
