This document provides definitions and examples of basic geometric concepts: points, lines, and planes. Points are defined as having position but no other attributes. Lines are composed of infinite points and have length but no other dimensions. Planes are flat surfaces that can contain infinite lines but have no thickness. Several activities are described to help students understand and apply these concepts, such as connecting points with lines, grouping pictures, drawing examples, and identifying examples in a classroom.

2. Using only 4 straight line, connect all 9
points without lifting your pen. I will give
you 2 minutes to answer it.
ACTIVITY 1

5. Direction: We have different pictures then group
it according to your observation. You have only 2
minutes to answer it. Paste your answer on the manila
paper.

9. 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.

10. 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.

11. The undefined terms are ,
and .

13. • Is point has a dimension or magnitude?
• Is point has a direction?
• Is point has a specific position?
NO
NO
YES

14. • Point is having specific position but
without dimension, magnitude, or
direction.

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

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

17. • Tip of a pen  Corner of a paper

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

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

23. 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.
A

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

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

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

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

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

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

32. 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

33. 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

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

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

37. 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.

38. 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.
