7. Everything must have a beginning. Considered as foundations of geometry, or any mathematical system for that matter, are postulates, assumptions, and theorems. But before these statements are established, definitions are needed.

8. Moreover, in defining terms, other terms are required to establish their definition. Otherwise, the system will be confined to a cyclic inquiry “what is the meaning of …”. This is the case where UNDEFINED TERMS are needed.

9. The undefined terms are points , lines and planes .

10. POINT

11. Is point has a dimension or magnitude? Is point has a direction? Is point has a specific position? POINTS NO NO YES

12. P oint is having specific position but without dimension, magnitude, or direction. POINT

13. • A dot is used to represent a point • A point is denoted by a capital letter. Example are A B C D POINT

14. The following real world objects illustrate a point • Keys of a cellphone POINT

15. • Tip of a pen POINT Corner of a paper

16. POINT

17. LINE

18. In constructing a line, we need to have two point. LINE A B Line is a one dimensional figures composed of infinite number of points. It has unspecified length but without width nor thickness .

19. The following real world objects illustrate a line • Edge of a cellphone LINE A straight string Edge of a bond paper

20. LINE

21. A plane is usually represented by a flat surface where infinite number of lines can lie. It has unspecified width and length, but without thickness . PLANE A

22. The following real world objects illustrate a plane • Screen of a cellphone PLANE A white board Flooring of a romm Wall

23. PLANE

24. Draw materials/things that are examples of point, line and plane. Make your output creatively. I will give 10 minutes to finish your output.

25. I will ask the question and write your answer on your mini board. ACTIVITY 4 Individual

26. 1. What do you call the undefined terms having specific position but without dimension, magnitude, or direction? Point

27. 2. What do you call the undefined terms that is a one dimensional figure composed of infinite number of points? Line

28. 3. It is usually represented by a flat surface when infinite number of lines can lie. Plane

29. 4-10. Identify if it is point , line , and plane . 4. screen of an ipad 5. stretched wire of a phone charger 6. mole on the human body Point Line Plane

30. 4-10. Identify if it is point , line , and plane . 7. Tip of a crayon 8. intersection of a wall and floor 9. edge of the bond paper 10. flat surface of a table Point Line Line Plane

31. Write at least 3 examples of each point, line and plane inside our classroom. I give you 2 minutes to do it. ACTIVITY 5 Group

32. “Starting point of success is to love yourself first and everything else falls into line” - by Lucille Ball

33. It all start with you. Loving yourself means loving all your flaws, your weaknesses and everything about you. With loving yourself with contentment is a success itself. If you love yourself then things happened positively.

34. Draw your own room in your house then identify those examples of point, line and plane. Use a short bond paper and make it creative. Rubrics : Creativity - - - - - - - - - - - - 30% Relativity- - - - - - - - - - - - - 50% Number of undefined terms-20% Total- - - - -100% ASSIGNMENT
