Do you know the general equation of a circle?
signal fable
yeah, ive worked out everything until the equation of the perpendicular bisector of the chord AB but i dont know what to do from after that
elder nymph
Okay, here's a fact that you need to know: the perpendicular bisector of a chord of the circle passes through the centre of the circle
Do you think you can use that information to help you progress?
Here's a tip, work out the equation of a second chord's perpendicular bisector
signal fable
if i work out the equation of the other chords bisector and they both pass through the center can i solve simultaneously to find the center or no?
elder nymph
Yes that's it!
signal fable
ohhh shit ty ty
elder nymph
No problem
