Three collinear points don't define a plane.

"Define" means narrow it down to one and only one unique plane, so that it can't be confused with any other one.

There are many different planes (actually infinite) that can contain three collinear points, so no unique plane is defined.

How many points are needed to define a unique plane Are they any restrictions on the location of these points?

A unique plane is defined by three non-collinear points. This means that the points must not all lie on the same straight line. If the three points are collinear or if only two points are given, they do not suffice to define a unique plane. Thus, the key restriction is that the three points must be non-collinear.


Can three noncollinear points be contained on one plane?

Yes. You require three non-collinear points to uniquely define a plane!


What plane contains points EF and G?

To determine the plane that contains points E, F, and G, we need to know their specific coordinates or how they are related in a geometric context. If these points are not collinear, they define a unique plane in three-dimensional space. If they are collinear, they do not define a plane by themselves. Please provide additional information about the points for a precise answer.


Can 3 collinear points define a plane?

No, they have to be noncolinear, that is they all can't be on the same line.


If four points are collinear they are also coplaner?

I dont think that "If four points are collinear they are also coplaner," is the same thing as "If four points are coplaner they are also collinear,". The definition of collinear is at least three points on the same line. To define a plane is to have threenoncollinear points.


How many different lines are determined by 3 non collinear points?

Any three non-collinear points will define a single plane. A plane is composed of an infinite number of distinct lines.


Are three non collinear point contained in exactly one plane?

Yes, three non-collinear points are contained in exactly one plane. By definition, non-collinear points do not all lie on the same straight line, which allows them to define a unique plane. In geometry, any three points that are not collinear will always determine a single plane in which they lie.


If four points are collinear they are also coplanar True or false?

True. If four points are collinear, they all lie on the same straight line, which means they can also be contained within a single plane. In geometry, any set of collinear points is inherently coplanar, as you can always define a plane that includes them.


How many of non collinear points in plane?

Infinitely many. There are infinitely many points in the plane and although any pair of points define a line, no matter how many lines you are given, it is always possible to find a point that is not on any of them - that is, a point that is not collinear.


Can noncollinear parts lie on the same plane?

Yes. In fact any three points that are not collinear define a plane and therefore MUST lie on a plane.


Do 3 non collinear points lie in at least one plane?

Three non-collinear points always define exactly one and only one plane. That's why a 3-legged table or chair never wobbles.
