Lecture 19 (Geometry) Solid Geometry or Space Geometry

In this geometry, the first postulate about space asserts that there exist:

1. A.At least three non-collinear points lying in one plane.
2. B.At least four points that are not all coplanar.
3. C.Exactly one plane that fills the whole of space.
4. D.Infinitely many parallel planes through any point.
