What is arc meaning?

The arc is a curved line that is part of a circle or other curved shape. It can represent a portion of a circumference, measured in degrees or radians, or a segment of a curved line. Arcs are commonly used in geometry, trigonometry, and mathematical analysis to describe angles and curves in two and three-dimensional objects. They are also used in architecture, design, and engineering to create the curves and arches found in buildings, bridges, and other structures. Additionally, the term "arc" is used in literature and storytelling to describe the progression of a character or plot.
