3 non collinear points say A,B,C
From 3 non collinear pints you can draw a triangle which can inscribes in a circle

How to do ?
Join AB and BC. Draw perpendicular bisector of AB and BC. The point where they will meet is circumcentre say O and with radius OA draw circle passing through 3 points

This will be a unique circle
