This slide show was prepared to help my fourth grade class learn about points, lines, and planes as part of our geometry unit in math and to help them with their homework.

1. POINTS, LINES, & PLANES TOPIC 9 Lesson 9-1

2. POINTan exact location in space A

3. LINEa straight path of points that goes on and on in two directions

4. PLANEan endless flat surface

5. PARALLEL LINES never intersect

6. PERPENDICULAR LINESform square corners with right angles.

7. INTERSECTING LINESpass through the same point

8. What kind of lines are these? Parallel Intersecting Perpendicular Go to the next slide to check your answer.

9. B. INTERSECTING Were you correct?

10. What kind of lines are these? Perpendicular Parallel Intersecting Go to the next slide to check your answer.

11. B. PARALLELWere you correct?

12. On the line, what is K called? Point Intersecting line Parallel line K

13. A. POINTWere you correct?

14. What kind of lines are these? Intersecting Parallel Perpendicular Go to the next slide to check your answer.

15. A. INTERSECTINGANDC. PERPENDICULARWere you stumped or did you figure it out?

16. Which 2 lines are parallel? A C E F H G AE and FG OR AE and CH

17. Did you guess AE and FG?You were correct!You’rea star!

18. Which 2 lines are perpendicular? MP S O RN MR and PN OR MR and OS

19. Did you guess MR and OS?You were correct!

20. Now you are ready to do your homework.
