What to Focus On

  • A circle is a closed curve of points at equal distance from the centre.
  • Radius is the fixed distance from the centre to the circle.
  • Diameter is a chord through the centre and is twice the radius.

  • Concentric circles have the same centre but different radii.
  • Equal circles have equal radii and are also called congruent circles.
  • A circumscribed circle passes through all vertices of a polygon.

  • An arc is a part of the circumference.
  • Default meaning of arc is minor arc.
  • A minor arc is smaller than a semicircle.

Common Mistakes to Avoid

Any line from the centre to a chord always bisects the chord and is perpendicular to it.

The word arc always means the bigger arc.

Equal circles means circles that look the same size on paper.
