Once you've specifically chosen to have a circle, as the OP did, it's
completely defined by three points.
You are right that the opposite is not true - given three points, you
can draw shapes other than a circle - but I didn't say that one couldn't.
BTW, a solution is described here (among other numerous places):

Three points can define any conic section - parabola, ellipse, or

Beziers are defined by four points, and OP has three.
A circle, on the other hand, is completely defined by three points
(except in degenerate cases: points on top of one another, or on a
straight line).
So if it's a circle segment (== arc) you want, derive its center and
radius (and arc angles) from your points.

Hi folks,
I would like to draw a curve(an arc) connecting three points in my
screen
PointA = (480,46) PointB = (160,137) PointC = (0,228)
How to draw the curve using Android APIs ?
Please Help..
You may want to check Path.cubicTo to generate a Bezier curve:
