What to Focus On

  • A circle is the set of all points equidistant from the centre.
  • All radii of a circle are equal.
  • A chord joins any two points on a circle.

  • Points inside the circle are interior points.
  • Points outside the circle are exterior points.
  • Points on the circle are neither interior nor exterior.

  • Concentric circles have the same centre and different radii.
  • Congruent circles have equal radii.
  • Concentric circles are not the same as congruent circles.

Common Mistakes to Avoid

Every chord of a circle is a diameter.

Any point on the circle is inside the circle.

The radius is half the chord length for every chord.
