Study Notes
Geometric Postulates
- Postulate 5: Intersecting planes will always intersect along a single line.
- Postulate 2: Through any two distinct points, there exists a unique line.
- Postulate 1b: Space must contain a minimum of four points that are not co-planar.
- Postulate 3: A configuration of three non-collinear points determines exactly one plane.
- Postulate 4: If two points lie in a plane, then the line connecting them is also within that plane.
- Postulate 1a: A plane must contain at least three points that are not collinear.
- Two points determine exactly one line.
- Theorems cannot be used to establish postulates; postulates are accepted truths.
- Theorems require formal proofs to validate their statements.
- Two planes intersect in only one line.
- If a ray lies in a plane, every point along that ray also exists in the same plane.
- If point C lies between points A and B, the segment lengths satisfy the equation AC + CB = AB.
- Three points may be collinear under certain conditions, but it is not a necessity.
- It is never true that two planes can intersect at only one point; their intersection is always a line.
