The term "centre" refers to the middle point of an object, area, or concept. It is the point that is equidistant from all edges or boundaries, making it a focal point for balance and symmetry. In geometry, the centre of a circle is the point from which all points on the circumference are equally distant. In various contexts, the centre can also represent a central authority or hub of activity. For example, a city centre is the main area where businesses, cultural institutions, and public services are concentrated, serving as a gathering place for residents and visitors alike.
