Also known as round shape, 1-sphere, circle line, non-filled circle

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. The distance between any point of the circle and the centre is called the radius. The length of a line segment connecting two points on the circle and passing through the centre is called the diameter. A circle bounds a region of the plane called a disc.

AI overview

A circle is a perfectly round shape made up of all points that sit at the same distance from a central point, called the radius. Circles are fundamental geometric shapes that appear throughout mathematics, nature, and everyday life, making them essential for understanding everything from engineering and astronomy to art and design.
