Yes. That's why a 3-legged stool never wobbles.
Yes. Every line has an infinite number of distinct points.
If they lie in the same plane.
all of them are collinear they lie in the same plane
a line that passes through two lines in the same plane at two distinct points
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
lie on the same plane and are collinear
Sometimes.
3 points must always be contained in one plane, as 2 make a line, it makes no difference as to where the third point is, it will exist in the same plane in the two. Aside from all three points being in a line, this is always true.
Points or lines that lie on the same plane are coplanar.
Definition of Coplanar points: Coplanar means that the points are on the equal plane. Plane is a two-dimensional object, with as such is a bit more complicated.Collinear,line,plane and point are the related terms of coplanar.Points that are on the same plane. 2 points are alwayscoplanar...3 points are always coplanar...4 points are sometimes coplanar.
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.
