Definition--Circle Concepts--Circles on a Coordinate Plane	Circles on a Coordinate Plane Topic Circles Definition Circles on a coordinate plane are defined by their center coordinates and radius. Description Understanding circles on a coordinate plane is essential for analyzing geometric shapes in a mathematical context. This concept is widely used in computer graphics, navigation systems, and physics simulations, where precise positioning and movement of circular objects are required. The standard equation of a circle in the coordinate plane is (x − h)2 + (y − k)2 = r2	Definition of a Circle
