order of rotation of a semi circle is 1
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
An arc that lies between the sides of a central angle of 180 degrees is known as a semicircle. A central angle of 180 degrees is half of a full circle, so the corresponding arc covers half of the circumference of the circle. In geometric terms, a semicircle is a special case of an arc where the angle subtended by the arc is exactly 180 degrees.
If the arc is circular, such a figure is a semicircle or half circle.
It is a right angle.
