Meaning and Definition
A drawing instrument with a fixed central pivot and two legs, used for drawing circles or arcs, where the legs are connected by a bow-shaped mechanism, often with an adjustable radius.
A precision drafting tool used in technical drawing, engineering, and architecture. The term can also refer loosely to any compass used for drawing circles, though technically it specifies a type with a rigid, often spring-loaded or screw-adjusted, bow-shaped frame for stability and fine control.
