Expert Answer:

dear student,
for any point to lie on a circle with given centre and radius,
we must have that the dist between the point and the centre is equal to radius.
here we are not given the radius.
so we will just see if the dist bet the centre and  each point is equal or not, if yes then they all lie on the same circle .o wise they do not lie on the same circle.
dist bet centre O and point A
=
dist OB
=
OC=
The distance between these points and the centre given is not equal.So these points do not lie on the same circle.
