A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.
I know that radius, cord and diameter are
Diameter
-The diameter of a circle is a line segment that passes through the centre of the circle and has its endpoints on the circle. All the diameters of the same circle have the same length.
Cord
- A chord is a line segment with both endpoints on the circle. The diameter is a special chord that passes through the centre of the circle. The diameter would be the longest chord in the circle.
Radius
-The radius of the circle is a line segment from the centre of the circle to a point on the circle. The plural of radius is radii.
