Topics 5
- Tangent is perpendicular to the radius at the point of contact
- Tangents from an external point are equal; touching circles and the line of centres
- Intersecting chords (internally and externally): product of segments
- Chord and tangent meeting externally: product of segments equals square of tangent
- Alternate segment theorem
