What to Focus On

  • Circle means all points at a fixed distance from a fixed point.
  • A line and a circle have only three possible positions.
  • Non-intersecting line: no common point.

  • A tangent is perpendicular to the radius at the point of contact.
  • The radius through the point of contact is called the normal.
  • The radius is the shortest distance from the centre to the tangent line.

  • Only one tangent can be drawn at a point on the circle.
  • The perpendicular to a tangent at the point of contact passes through the centre.
  • These results follow from uniqueness of the perpendicular.

Common Mistakes to Avoid

A tangent and a secant are completely different types of lines with no connection.

Any line near a circle is a tangent if it does not pass through the circle.

A line intersecting a circle at two points does not form a chord.
