A semicircle has 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.
An angle whose measure is exactly 180 degrees is a straight angle.
An angle of 180 degrees is a straight line.

If the arc is circular, such a figure is a semicircle or half circle.

There are 180 degrees in a semi-circle.
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.
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
