In Maths or Geometry, a circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the centre. The distance from the centre of the circle to the outer line is its radius.
What is Circle? 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 the locus of points which moves in a plane such that its distance from a fixed point is always constant. The fixed point is called the ‘centre’ while the fixed distance is called the ‘radius’. This article will help you to have a clear idea of the topics such as circle, equation of tangent, normal and chord of contact.
A circle is a set of all points which are equally spaced from a fixed point in a plane. The fixed point is called the center of the circle. The distance between the center and any point on the circumference is called the radius of the circle.
Jun 20, 2024 · Circle Definition. A circle is a collection of points in a plane that are equidistant from a given fixed point. The fixed point is called the centre of the circle. And the fixed distance from the centre is called the radius of a circle.
Explore, prove, and apply important properties of circles that have to do with things like arc length, radians, inscribed angles, and tangents.
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):
