    Can anyone help me with this question? It gives you a circle and you're asked to find the centre and state what theorems you used.

    What I would do is draw 2 chords, draw their perpendicular bisectors, and the point of intersection of these bisectors would be the centre of the circle.

    Theorem: the perpendicular bisector of a chord passes through the centre of a circle
