A plane
Three noncollinear points ( A ), ( B ), and ( C ) determine exactly three lines: line ( AB ), line ( BC ), and line ( AC ). Each pair of points defines a unique line, and since the points are noncollinear, no two lines coincide. Thus, the total number of lines determined by points ( A ), ( B ), and ( C ) is three.
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.

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