Section 2.4 Use Postulates and DiagramsMore Postulates:Postulate 5: Through any two points there exists exactly one line.Postulate 6: A line contains at least two pointsPostulate 7: If two lines intersect, then their intersection is exactly one point.Postulate 8: Through any noncollinear points their exists exactly one planePostulate 9: A plane contains at least three noncollinear pointsPostulate 10: If two points lie in a plane, then the line containing them lies in the planePostulate 11. If two planes intersect, then their intersection is a line
State the postulate illustrated by the diagram:a.b.
Use the diagram to write examples of Postulates 9and 10.
Use the diagram to write examples of Postulates 6 and 8Use the diagram in Example 2. Which postulate allows you to say that the intersection of plane Pand plane Q a line? Use the diagram in Example 2to write examples of Postulates 5, 6, and 7is .
Interpreting a DiagramYou can Assume: All point shown are coplanarAHB and DHB are a linear pair
