A plane
You have to have three or more points to have non-colinear points because any two points determine a line. Noncolinear are NOT on the same line.

Three noncollinear points A, B, and C determine exactly three lines. Each pair of points can be connected to form a line: line AB between points A and B, line AC between points A and C, and line BC between points B and C. Thus, the total number of lines determined by points A, B, and C is three.

Two. Two points determine a line. Three points determine a plane.
noncollinear
You need two points to determine a line. A single point can have an infinite number of lines passing through it.
