Line Segment AB bisects Chord DE.
Move Point A so that AB goes through the centre of the circle.
What do you notice about the angle?
The Rule: If a bisector of a chord in a circle passes through the centre, then the bisector is perpendicular to the chord.
The Big Picture:
- perpendicular
- bisector of chord
- through centre of circle
if two of these are true then all three are true.
