Are four planes are coplanar?
Four planes are not necessarily coplanar. For four planes to be coplanar, they must all intersect along a common line or within the same two-dimensional space. In general, three planes can intersect at a single point or line, but adding a fourth plane may cause it to not share the same intersection, thus not being coplanar. Therefore, unless specific conditions are met, four planes typically do not lie in the same plane.
If four points are coplanar then they are also collinear?
not necassarily
Which is determined by four non-coplanar points?
space
What is determined by four non-coplanar points?
life
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.
The number of tangents that can be drawn to two nonintersecting circles is?
The answer is four. Wish I could draw a picture.
Four points are always coplanar if?
all of them are collinear they lie in the same plane
If four points are coplanar then they are noncollinear?
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.
Is it true that the four coplanar points determine three unique plane?
No. If the four points are coplanar, they determine only one plane!

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, since any line can be contained in a plane.
