Three.
3 non-collinear points define one plane.
3 or more
1, exactly 1 plane will
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.
Three.
3 non-collinear points define one plane.
Any Euclidean plane has infinitely many points.
3 or more
1 line cause every plane contains atleast 3 or more noncollinear points
1, exactly 1 plane will
just one
The answer depends on the number of point. One point - as the question states - cannot be non-collinear. Any two points are always collinear. But three or more points will define a plane. If four points are non-coplanar, they will define four planes (as in a tetrahedron).
4 points define a plane.
3
Only one plane can pass through 3 non-collinear points.
They define one plane. A line is defined by two points, and it takes three points to define a plane, so two points on the line, and one more point not on the line equals one plane.
