A circle with centre O, diameter AB and a chord AD is drawn. Another circle is drawn with AO as diameter to cut AD at C, then BD = 2 OC.
BD = 2 OC
BD = OC
2BD = OC
BD =3 OC
A circle is drawn with AB as the diameter whose endpoints are A(2,4) and B(4,12). If another circle with diameter one-third of the above circle is drawn with the same centre, what are the points that the circle cuts AB?
