Yes, a plane can be uniquely defined by three points as long as the three points are not colinear. (Three points are colinear if there is a straight line that passes through all three points.)

Can three noncollinear points be contained on one plane?

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


How can you name a line and a plane?

Here is one option: 2 points uniquely define a line so a line can be named after any two points that belong to it. Similarly, three points that are not collinear (all in the same line) uniquely define a plane so a plane can be defined by naming any three non-collinear points in it. There are different - though related - forms in coordinate geometry or in vector algebra.


If three distinct points are not col-linear how many planes can possibly contain the three points?

Three non-co-linear points are sufficient to uniquely define a single plane.


Why is a plane not defined by three given points?

it is, unless all three points are in the same line (Your "Why" should have be "When")


Does a line lie in only one plane?

No. A line can lie in many planes. A plane can be defined by three non-linear points. Since a line is defined by only two points, we need another point. (Note that point C alone, or line AB alone belong to an infinite number of planes.)


Are three collinear points coplanar?

Yes. Three co-linear points define a line, and therefore also lie on a plane, but those three points do not necessarily define only one plane. You need three points, not co-linear, to uniquely define a plane. See Related Links below for more information.


How many non-collinear points are needed to create a plane?

To create a plane, infinitely many. To uniquely determine a plane, just three.


Infinite width and length and can be determined by three points?

The shape described is a plane, which is a two-dimensional surface that extends infinitely in both width and length. In geometry, a plane can be uniquely determined by any three non-collinear points on the plane. This is known as the "three-point" or "unique determination" property of a plane. The three points define the plane's orientation and position in three-dimensional space.


How many planes can be formed with four non collinear points?

Four non-collinear points can form exactly one plane. This is because a plane is defined by three non-collinear points, and adding a fourth point that is not in the same line as the other three does not create a new plane; rather, it remains within the same plane defined by the initial three points. Therefore, all four points lie in the same unique plane.


How many points make up a plane?

A plane is defined by at least three non-collinear points. While an infinite number of points can exist within a plane, the minimum requirement to determine a unique plane is three points that do not all lie on the same straight line.


How many points are used to define a plane?

A plane in three-dimensional space is defined by three non-collinear points. If the points are collinear, they do not define a unique plane, as an infinite number of planes can pass through a line. Therefore, at least three points that are not on the same line are necessary to establish a distinct plane.


What is advantage of three legged stool?

A plane is defined by three points, so a three legged stool is stable because the points on the end of the stool's legs are coplanar
