Final answer:
An arc can be classified as a major arc, minor arc, or a semicircle based on its length and position on the circle.
Step-by-step explanation:
An arc can be classified as a major arc, minor arc, or a semicircle based on its length and position on the circle.
A major arc is an arc that measures more than 180 degrees, which means it covers more than half of the circle.
A minor arc is an arc that measures less than 180 degrees, which means it covers less than half of the circle.
A semicircle is a special type of arc that exactly measures 180 degrees, which means it covers exactly half of the circle.
