Circle – Introduction A circle is a shape with all points at the same distance from its center. This distance is called the radius. Let’s break this down with diagrams and examples: Definition of a Circle Circle: A set of all points in a plane that are equidistant from a fixed point, called the center. […]

Circumscribed circle In geometry, the Circumscribed circle or circumcircle of a polygon is a circle that passes inside a circle in such a way that all its vertices lie on the circle, or just touch the circle. Centre of this circle is called circumcenter and its radius is called […]
