They need not be. The four vertices of a quadrilateral are coplanar but NOT collinear.
On the other hand, any line (in Eucledian geometry) has an infinite number of points on it - all of which are coplanar.

If three points are coplanar then are they collinear?
Not necessarily. Coplanar means that points lie on the same plane whereas collinear means that points lie on the same line. Points on a plane do not necessarily lie along the same line.
What are two coplanar lines called that have no points in common?
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
What are noncollinear points?
This is a geometry term. It's a point that does not pass or lie on the same line as another point.
What is a line that intersects two or more coplanar lines at different points?
It is a tranversal.
Are vertical angles coplanar?
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
Are four noncollinear points always coplanar?
No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
Four points are always coplanar if?
all of them are collinear they lie in the same plane
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).
Is it true that the four coplanar points determine three unique plane?
No. If the four points are coplanar, they determine only one plane!
4 points are always coplanar?
Three points are, but not four.
A triangle is a figure formed by three segments and four coplanar points?
No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
A line and a point not on the line are never coplanar?
No, they always are From Wikipedia.org, "The World's Encyclopedia" when I searched coplanar In geometry, a set of points in space is coplanar if the points all lie in the same geometric plane. For example, three distinct points are always coplanar; but four points in space are usually not coplanar. Since 3 points are always coplanar. A point and line are always coplanar
If four points are collinear they are also coplanar.?
Yes, they are.
If four points are collinear are they also coplanar.?
Yes, they are.
Which is determined by four non-coplanar points?
space
If four points are coplanar then they are also collinear?
not necassarily
What is determined by four non-coplanar points?
life
