Understanding Circle Arcs
A circle arc is a part of the circumference of a circle that is bounded by two points on the circle. Imagine it like a piece of string that curves following the shape of the circle. When we have a circle and mark two points on it, the part of the circumference that connects these two points is called an arc.
Each arc has two endpoints located on the circle, and the length of the arc depends on the size of the central angle that faces the arc. The larger the central angle, the longer the arc.
