Best Answer

The tail of the typical airplane is made up of two horizontal wings which are called the horizontal stabilizers. the have flaps in the back of them that will stabilize the attitude of the plane at varying speeds. without it it would never get of the ground or stay in the air. The wing that points upwards is the vertical stabilizer and can be compared to the keel on a boat it will control the direction that the plain is pointed in.

What do three points form in geometry?

A plane is named by three points in the plane that is not on the same line.


How many points make a plane?

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 points that determine a plane?

Any 3 points determine a plane.


Can each plane be uniquely defined by three points?

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.)


What determines a plane?

three points can determine a plane


How many points are needed to determine a unique plane?

A plane can be determined by three points, as long as the three points do not lie along a single line.


Does a plane have only two points?

No, two points define a line. It takes three points to define a plane.


Can three noncollinear points be contained on one plane?

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


Is every set of three points coplanar?

Yes, three points define a plane. So any three points lie in some specific plane and are therefore co-planar.


What are points that lie on the same plane?

Points that lie on the same plane are coplanar. Generally, three points have to be coplanar, but more than that can be in any plane.


Are three noncollinear points always contained in only one plane?

Yes a plane can always be drawn three any three points, whether they are linear or not.


When would three points not determine a plane?

A series of 3 points will always determine a plane unless 2 or all 3 points are identical points (they have the same coordinates).If the idea is to have the three points determine oneplane, a unique plane, then three points will do that as long as none of them have the same spacial coordinates (have identical locations) or as long as the three points do not lie on a single line.If a straight line can be drawn through all three points, they will not form one unique plane either.
