Circle:-

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. Every line that passes through the circle forms the line of reflection symmetry. Also, it has rotational symmetry around the centre for every angle. The circle formula in the plane is given as:

"(x-h)² + (y-k)² = r²"

Parts of circle:-

A circle has different parts based on the positions and their properties. The different parts of a circle are explained below in detail.  

  1. Annulus-The region bounded by two concentric circles. It is basically a ring-shaped object. See the figure below.
  2. Arc – It is basically the connected curve of a circle.
  3. Sector – A region bounded by two radii and an arc.
  4. Segment - A region bounded by a chord and an arc lying between the chord’s endpoints. It is to be noted that segments do not contain the centre.
