If the arc is circular, such a figure is a semicircle or half 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.
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 arc that measures less than a semicircle is called a minor arc. In a circle, a minor arc is defined as the shorter of the two arcs connecting two points on the circumference. It is less than 180 degrees in measure, while the corresponding longer arc is known as a major arc.
