Circle Theorems II
Bayani Gaba-gaba
Beyond the angle theorems, circles have neat symmetry properties about their chords and tangents. These let you find lengths and prove that certain lines pass through the centre.
In this lesson you will use the property that tangents from an external point are equal in length (Core), and (at Extended) that equal chords are equidistant from the centre and the perpendicular bisector of a chord passes through the centre.
Manufura
- Use the symmetry property of circles that tangents from an external point are equal in length.
- Use the following symmetry properties of circles: equal chords are equidistant from the centre the perpendicular bisector of a chord passes through the centre tangents from an external point are equal in length. (Extended only)
