Presentation transcript:

 Identify postulates using diagrams.  Identify and use basic postulates about points, lines, and planes.  A postulate or an axiom is a statement that is accepted as true without proof.

Through any two points there exists exactly one line.

A line contains at least two points.

If two lines intersect, then their intersection is exactly one point.

Through any three non-collinear points, there exists exactly one plane.

A plane contains at least three non-collinear points.

If two points lie in a plane, then the line containing them lies in the plane.

If two planes intersect, then their intersection is a line.
