A circle is a two-dimensional figure formed by a set of points that are at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed shape , two-dimensional shape, curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop.
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 circle has been known since before the beginning of recorded history. Natural circles are common, such as the full moon or a slice of round fruit.
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. […]
In geometry, a circle is defined as a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “ center .” Never confuse a circle with a polygon. A circle is not a polygon because it is made up of curves. The history of the circle is ancient.
Definition. Circle: the set of all points on a plane that are a fixed distance from a center. Area. The area of a circle is π times the radius squared, which is written: A = π r 2. Where. A is the Area. r is the radius. To help you remember think "Pie Are Squared" (even though pies are usually round):
a continuous curved line, the points of which are always the same distance away from a fixed central point, or the area inside such a line: Coloured paper was cut into circles. We sat in a circle.

Explore, prove, and apply important properties of circles that have to do with things like arc length, radians, inscribed angles, and tangents.
noun. a closed plane curve consisting of all points at a given distance from a point within it called the center. Equation: x 2 + y 2 = r 2 . the portion of a plane bounded by such a curve. any circular or ringlike object, formation, or arrangement: a circle of dancers. Synonyms: corona, halo, ring. a ring, circlet, or crown. the ring of a circus.
