Given three points, is it possible to construct a circle with all three on its circumference?
Only if they are concentric.
Only if they are non-collinear.
Only if they are in the same plane.
Give a geometrical construction for finding the fourth point lying on a circle passing through three given points, without finding the centre of the circle. Justify the construction.
Through any given set of three distinct points A, B, C it is possible to draw at most ___circle(s).
