How many planes can be determined if the point noncollinear?
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).
If four points are coplanar then they are also collinear?
not necassarily
Can three non collinear points make a circle?
yes, any three non collinear points will make a circle, however, four or more will not
Four points are alwats coplanar if they?
-lie in the same plane -are collinear
How do you draw four noncollinear points?
-- The four corners of a square are non-collinear. -- The four corners of a rectangle are non-collinear. -- The four vertices of any rhombus, parallelogram, or quadrilateral are non-collinear. -- Any four vertices of any polygon with more than 3 sides are non-collinear. -- The three vertices of any triangle are non-collinear, and they stay that way when you add any other point on the same piece of paper. -- Any four points on any circle, ellipse, parabola, or hyperbola are non-collinear. -- If at least one point is on a different floor of the house from the other three, then the four points are non-collinear. -- Make three dots on a piece of paper. Cover them up. Walk away for a few minutes. Come back. Make another dot on the paper. Uncover the first three. We're almost positive that the four dots are non-collinear.
