Finding the centre of a circle - Esther, Dawn & Dylaine

To find the centre of the circle, we drew a chord of the circle, then drew an arc from each of the two end points of the chord of the same radius length. From the two intersecting points formed by the arcs, we were able to construct a diameter of the circle, from the Bisecting Chord Theorem (perpendicular bisector of chord is diameter).

This was repeated to find another diameter, in which the intersection with the first diameter is the centre of the circle.
