Post-It Notes - 1.3 Points, Lines, and Planes
- 2. Take one of each of the following colors: pink, orange, yellow, and green. Take 4 of the blue post-its.
- 3. Pink Post-It Naming a Line Under the Post-It You can name a line by any two points on the line or with a single lower case letter. A B t
- 4. Orange Post - It Identifying Collinear Points Under the Post-It Points E, F, and C are collinear on line m. Points E, F, and D are not collinear. l m D C n E F P
- 5. Yellow Post-It Under the Post-It Each surface of the box represents part of a plane. You can name a plane by using at least 3 noncollinear points. Example: plane AEF Naming a Plane A D C B E G F H
- 6. Green Post-It Finding the Intersection of Two Planes A D C B E G F H
- 7. Blue Post-Its Postulate 1-1 Through any two points, there is exactly one line. Postulate 1-1 t A B Line t is the ONLY line that passes through points AB.
- 8. Blue Post-Its Postulate 1-2 If two lines intersect, then they intersect in exactly ONE point. Postulate 1-2 D B A E C
- 9. Blue Post-Its Postulate 1-3 If two planes intersect, then they intersect in exactly one line. Postulate 1-3 S T R W
- 10. Blue Post-Its Postulate 1-4 Through any three noncollinear points, there is exactly ONE plane. Postulate 1-4 Through any three noncollinear points, there is exactly one plane. A B C
