What to Focus On

- OP is the shortest distance from the centre to the tangent line.
- If a point on a tangent lies inside the circle, the line becomes a secant.
- Inside the circle: no tangent.
- On the circle: exactly one tangent.
- Outside the circle: exactly two tangents.
Common Mistakes to Avoid
