Define what an arc is in the context of a circle.

An arc in the context of a circle is a segment of the circumference that connects two points on the circle. Imagine taking a slice of your favorite pizza; the crust along the edge of the slice represents the arc, curving between the two points where your slice meets the pizza pie! The length of this arc can vary depending on the angle subtended at the center of the circle. Arcs can be classified as minor or major, depending on their size relative to the circle. A minor arc is the shorter path between the two points, while the major arc takes the longer route around the circle. A fun fact: the names of the arcs often come from the angles—if the angle is less than 180 degrees, it's a minor arc, and if it’s more, then you’re boldly venturing into major arc territory!
