A plane can be determined by three points, as long as the three points do not lie along a single line.
Yes, three points determine a plane unless they are in a straight line. A plane is two dimensions a line is only one. You need a third point(not in the line) to define a plane.
Just one plane.
3 non-collinear points define one plane.
A plane is named by three points in the plane that is not on the same line.
Any three non-collinear points will define a single plane. A plane is composed of an infinite number of distinct lines.
It takes three points to make a plane. The points need to be non-co-linear. These three points define a distinct plane, but the plane can be made up of an infinite set of points.
