Learn moreA circle is one of the geometrical shapes which has no corners or edges.
Parts of the circle:
Circumference: The distance once around the circle.
Circular arc: A part of the circumference of a circle .
Sector: The plane surface that is enclosed between two radii '\(r\)' and the circular arc of a circle .
Chord: A line segment joins any two-point \(A\) and \(B\).
Diameter: A chord \(A\) and \(B\) passing through the centre of a circle \(O\). it also knowns as the longest chord.
Radius: A distance from the centre \(O\) to the circumference.
Segment: A chord divide the circle into two parts. Then that each part is termed as segments. In this, the smaller arc is known as a minor segment, and the larger arc is known as a major segment.
Concentric circles: A circle has the same centre but different radii.
