In the problem, the centre just needs to be located.

However:

1. Construct circle A1, centred on the circumference of the given circle, O1, intersecting it at B and C.

2. Construct circles B1 and C1, centred on B and C, both passing through A, and another point, D.

3. Construct circle D1, centred on D, and passing through A. This circle intersects A1 at E and F.

4. Construct circles E1 and F1, centred on E and F, and passing through A. Their other point of intersection is then O, the centre of O1.
