Which type of arc measures exactly 180?

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.


Does a minor arc measure exactly 180 degrees?

No. Given two points on a circle, the minor arc is the shortest arc linking them. The major arc is the longest.


What describes an arc that lies between the sides of a central angle of 180?

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.
