The document covers the visualizing, identifying, and describing of polygons with five or more sides over a series of daily lessons. It provides definitions, properties of polygons, differentiates between regular and irregular polygons, and introduces the concept of congruence. Various activities and questions are included to help students match polygons with their corresponding number of sides, describe their properties, and visualize them.

Answers:
1. The base is 6,000
2. The rate is 10%
3. The percentage is 600.

3. Look at the different FIGURES and name
what FIGURE it is:

4. What did you observed to those
shapes being presented?
Open or closed figures?
Close figures.

5. The following figures showed is what we
call Polygons.
Polygons are closed plane figures that
are formed by the line segments that
meet only at their endpoints. The line
segments are the sides. The endpoints
where the sides meet are the vertices.

7. Everyday, we encounter representations of
polygons in many different forms, colors and
sizes, even in the streets or inside our homes.
Thus, knowing and identifying shapes and
angles are not enough. It is also important to
master the skills in visualizing, naming and
describing polygons with 5 sides or more, so
that we can easily recognize them wherever
we go, in whatever form and shape they are
having.

8. Remember that a three-sided
polygon is called a triangle.
A four-sided polygon is called a
quadrilateral.

9. A five-sided polygon is called
a pentagon.
A six-sided polygon is called a
hexagon.

10. A seven-sided polygon is called
a heptagon.
An eight-sided polygon is called
an octagon.

11. A nine-sided polygon
is called a nonagon.
A ten-sided polygon
is called a decagon.

12. An eleven-sided
polygon is called
an undecagon.
A twelve-sided
polygon is called
a dodecagon.

13. An n-sided polygon
can be called
n-gon.

14. Match the following polygons with
their corresponding number of sides:
A B
1. Triangle A. 6 sides
2. Quadrilateral B. 8 sides
3. Hexagon C. 3 sides
4. Octagon D. 10 sides
5. Decagon E. 4 sides

types of polygons?
What is the meaning of
polygon?

17. Visualize the following polygons
though drawing.

Describing and Comparing
Properties of Regular and
Irregular Polygons

34. Review:
Describe the following polygons according
to the number of sides.
1. dodecagon
2. hexagon
3. decagon
4. nonagon
5. octagon

35. Observe the following figures below;
What can you say
about the figures?

36. Can you consider those figures as
Polygons?
The following figures are non-polygons.
Can you tell, why?
Let’s Discuss it!

37. It is said that Polygons are identified
according to the number of sides that
they have.
And polygon is a closed plane figure
that is formed by the line segments that
meet only at their endpoints.

38. The following figures are examples of
polygons around us. Can you determine
what these are and where you typically see
them?

39. When working with
polygons the properties are
the number of sides of the
shape, the angles in the
shape, and the length of
the sides of the shape.

40. Observe the following sets of figures;

41. Can you see the difference
between the sets of figures?

42. The following are examples of regular
polygons;

43. A polygon which has all its
sides of equal length and
all its angles of equal
measures is called a
regular polygon.

44. The marks on the sides of the
polygons indicate equal length.

47. A polygon which sides are
not equal in length and all
its angles are not equal is
called a regular polygon.

48. Let’s Compare!
Compare the two figures
and tell whether regular or
irregular polygons

49. Which figure is regular
polygon?
Which is irregular polygon?

50. Know Me Well!
Write RP if ethe figure described regular
polygon and IP if irregular Polygon.

51. Give some examples of
objects that you always
use every day that shows
Irregular Polygons.

52. When can you say
that a polygon is
irregular and regular?

53. Directions: Read for each figure, count the
number of sides, name the polygon and describe
if it is regular or irregular.

Visualizing Congruent
Polygons

56. Review:

57. Are the set of figures the same?

58. For Set A the figures are the
same while set B are not the
same.
For Mathematical Term we can
say it as Congruent or Not
congruent.

59. Always remember that the word
“congruent” is defined as
“identical in form; coinciding
exactly when superimposed.” The
origin of the word “congruent” is
from the Latin to “agree” or “to
meet together”.

60. Congruent polygons are
exactly the same size and
exactly the same shape. All
of their sides have the same
length and all of their angles
have the same measure.

62. Polygons are congruent if they
are equal in all respects: same
number of sides; all
corresponding sides have the
same length; and all
corresponding interior angles
have the same measure.

63. It is possible to turn, flip and/or slide one
figure so it will fit exactly on the other
figure.
The areas of congruent figures are equal.
The perimeters of congruent figures are
equal. The corresponding angles of
congruent figures are equal in measure.

64. The corresponding line segments of
congruent figures are equal in length.
Congruent Figures
 These are pairs of figures which have
exactly the same size and shape.
 These figures have equal measures
for all the sides and angles.

65. Congruent Polygons
 Two polygons are congruent
if their corresponding sides
and angles are congruent.

66. Identify whether the following are
congruent polygons or not.

67. The two triangles have equal
measures of angles. However,
notice that the measures of their
sides are not equal. This means
that the two triangles are not
congruent.

68. Identify whether the following are
congruent polygons or not.

69. The tick marks indicate that
the corresponding sides of the
two triangles are congruent.
The second triangle is just a
rotated version of the first
triangle. Therefore, the
triangles are congruent.

70. Find My Pair!
Directions: Identify the figures that appear to
be congruent. Write your answer on a
separate sheet of paper.

72. On a sheet of paper, draw
a congruent polygon that
you can see on your
surroundings.

73. When can you say
that polygons are
congruent?

74. Directions: Choose the figure that is likely
to be congruent to the given figure. Write
your answer on a separate sheet of paper.
