Answer:
We know that line joining centre to then mid point of a chord is perpendicular to the chord. Therefore, if we are given a circle, we can draw to chords on it and construct their perpendicular bisectors, the meeting point of the two perpendicular bisectors will be centre of circle (see picture).
