What is a major arc?

A major arc is defined as a portion of a circle that measures more than 180 degrees. In other words, it is an arc that spans more than half of the circumference of a circle. Major arcs are often denoted by two points on the circumference of the circle, with a third point indicating the extent of the arc.

In terms of measurement, a major arc can range from 180 degrees to 360 degrees. A semicircle, for example, is a special case of a major arc that measures exactly 180 degrees.

Major arcs are commonly used in geometry and trigonometry to calculate angles, distances, and other measurements related to circles. They are also used in various applications such as architecture, engineering, and physics.
