1 TODAY IN GEOMETRY…  Learning Goal 1: 2.4 You will use postulates involving points, lines, and planes  Independent Practice

2 POSTULATE 5:POSTULATE 6: Through any two points there exists one line. A line contains at least two points.

3 POSTULATE 7:POSTULATE 8: If two lines intersect, then their intersection is exactly one point. Through any three noncollinear points there exists exactly one plane.

4 POSTULATE 9:POSTULATE 10: A plane contains at least three noncollinear points. If two points lie in a plane, then the line containing them lies in the plane.

5 POSTULATE 11: If two planes intersect, then their intersection is a line.

6 PRACTICE: State the postulate illustrated by the diagram. POSTULATE 7: If two lines intersect, then their intersection is exactly one point. POSTULATE 11: If two planes intersect, then their intersection is a line.

7 PRACTICE: Use the diagram to write examples of each postulate: POSTULATE 9: POSTULATE 10: A plane contains at least three noncollinear points. Plane P contains points noncollinear points B, A, C If two points lie in a plane, then the line containing them lies in the plane. Points A and B lie on Plane P, line n also lies on Plane P.
