A(2,-1) and B(4,3) are two points on a circle with centre (1,2). What is the distance of the chord from the centre of the circle? A step to step solution thanks

We don't give step-by-step solutions here. Have a go first, show us what you've done and where you're going wrong, then we'll be able to guide you in the right direction.
As for a place to start, sketch a small diagram of the circle, chord and the centre. I assume it wants the shortest distance from the chord to the centre which would mean you need to find a point on the chord (A) which makes OA perpendicular to the chord, then find the distance of this line.

So the midpoint of the chord is (3,1) so then do I need to find out the distance between (1,2) and (3,1) using the distance formula involving pythag
