You name it !
No solid lies in a plane.
false
In geometry, a solid cannot exist entirely in a plane because solids are three-dimensional objects, while a plane is two-dimensional. A solid has depth in addition to width and height, so while the base or projection of a solid can lie within a plane, the solid itself extends beyond the confines of that plane. Thus, a solid can intersect a plane but cannot be fully contained within it.
Yes.
they lie in the same plane
Skew lines cannot lie in the same plane.
Two lines can lie in one plane. For example, parallel lines are lines that intersect and lie in the same plane.
non-coplanar points are points that does not lie on the same plane... by:GRAETIA VILLANUEVA...
A straight line MUST lie in a plane. A curved line may or may not.
what is a solid
A solid has a depth, a plane figure does not.
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.
Yes. In fact any three points that are not collinear define a plane and therefore MUST lie on a plane.
