Explain why the perpendicular from the centre of a chord bisects the chord SSM2h
Possibly: The line which bisects a chord at right angles is always a diameterBut this isn’t in the Edexcel text??
Have I lost it, or is this not obvious?? Any line thro the centre of the chord will bisect the chord (NO?)
NOTESPupils should be able to describe how they find each angle.
