circular arc
Segment of circumference
A circular arc is a portion of a circle's circumference—the curved line connecting two points on a circle.
The term distinguishes this specific curve from arcs of other shapes like ellipses or parabolas.
In geometry and engineering, circular arcs are fundamental: The bridge spans the river in a single circular arc.
