What to Focus On

  • All points on a circle are at equal distance from the centre.
  • Radius means the distance from the centre to any point on the circle.
  • A chord joins two points on the circle.

  • A circle looks unchanged after any rotation about its centre.
  • Every diameter is a line of reflection symmetry.
  • Symmetry is used to study equal chords and equal distances from the centre.

  • Two points determine infinitely many circles.
  • The centres of those circles lie on the perpendicular bisector of the joining segment.
  • Three non-collinear points determine a unique circle.

Common Mistakes to Avoid

A circle is just a round shape, so any closed round figure is a circle.

Any line segment joining two points on a circle is a diameter.

The centre of a circle can be found by guessing the middle of its boundary by eye.
