III. PROCEDURES
A. Reviewing past lesson or
Presenting the new lesson
Group pupils into six teams.
Provide each group with the
definition of the different
kinds of lines and angles.
Flash the cards with
drawings one at a time and
let pupils post the meaning
on the board.
Drill: “Feeling Quiz Bee”
(Kinds of lines and angles)

Review: Let pupils recall the
relationship of a
quadrilateral and a triangle.
Let them give the
description of each.
Do you recall your lesson on
triangles? How do we
classify triangles? What are
the different kinds of
triangles? How do they
differ from one another?

important details of the
lessons
B. Establishing a purpose of the
new lesson
Let them look around. Ask
what shapes they can see.
Show the Philippine flag.
Ask: What can you see in

can you see?
Ask the different ways of
showing respect to the flag.
Elicit the value of
patriotism.






















continuously increasing.
Even prices of vegetables
are going up. Knowing that
they have to eat vegetables
to keep their family healthy,
Mr. and Mrs. Manalig
decided to have a vegetable
garden in their backyard.

What vegetables does the
Manalig family have in their
garden. They have celery,
saluyot, eggplant seedlings,
pepper and lettuce. Do you
also eat vegetables? Do you
think it is good to have our
own vegetable garden at
home?
Let us look at the containers
the Manaligs used in their
garden. Observe the shape
of the containers.

C. Presenting Examples/ instances
of the new lesson
Who am I?
-I am a closed figure made
up of several line segments.
(polygon)
-I am a three-sided polygon.
(triangle)
-I am a four-sided polygon
(quadrilateral)
Study the figure below.


All the containers used in
the garden of the Manalig
Family are rectangles in
shape.

They all have four sides and
four corners. These shapes
are also called
quadrilaterals.
All four-sided figures or

Giving of instructions.

3. 1. How many triangles do
you see? Can you see the
14 triangles in the figure?
Yes, there are 14
triangles in the figure.
Try to find those 14
triangles.
2. Are the sides and
angles of each triangle
equal?
If your answer is No, you
got it right!
polygons are called
quadrilaterals. Some of
them have two or more
equal sides.
Quadrilaterals may also
have one or two pairs of
parallel sides.
Although all quadrilaterals
have four sides, we can see
that they vary in sizes and
shapes.
Let us now look at the
different kinds of special
quadrilaterals.

D. Discussing new concepts and
practicing new skills no.1.
Group the figures below
into triangles and
quadrilaterals by putting
the figure to where it
belong.


Do you know that a
triangle is one of the
basic shapes of
Geometry?
It is a polygon with three
vertices and three sides
which are straight line
segments.







1. How many shapes do you
see in the puzzle?
2. Do all shapes look alike?
3. How many sides has each
shape?

What is a polygon?
(A polygon is a closed
figure made up of several
line segments that are
joined together.
✓ What do you call a
3-sided polygon?
✓ What about a 4-
sided polygon?
Do you know that a
triangle is one of the
basic shapes of
Geometry? It is a polygon
with three vertices and
three sides which are
straight line segments.


1. How many shapes do you
see in the puzzle?
2. Do all shapes look alike?
Parallelogram is a
quadrilateral with two
pairs of parallel sides. Its
opposite sides are equal.

4. This is triangle ABC.
You can also call it
triangle CBA or BCA or
ACB.
In symbols: ΔABC or
ΔBCA or ΔACB.
The point where two
sides meet is called
vertex.
Each segment is called a
side of the triangle.
Any two sides of the
triangle form the three
corners known as the
angles.
3. How many sides has each
shape?
Rhombus is a quadrilateral
that has 4 equal sides. It
has no right angles.

Rectangle is a
quadrilateral with two
pairs of parallel sides and
has 4 right angles. Its
opposite sides are equal.


Square is a quadrilateral
that has 4 equal sides and
4 right angles.



Trapezoid has only one
pair of parallel sides.

5. G. Developing Mastery
(Leads to Formative Assessment 3.)
The polygons inside the
box below include
triangles and
quadrilaterals.
Put a heart shape on
shapes considered as
triangles and a check on
quadrilaterals.


























A. Triangles can be
classified according
to their angles.
1. Right Triangle –
a right triangle
has a right angle
which measures
90°. ΔABC is a
right triangle.




2. Acute Triangle –
an acute triangle
has 3 acute
angles, each
measure less
than 90°. ΔDEF
is an acute
triangle.





3. Obtuse Triangle
– an obtuse
triangle has an
obtuse angle
which measures
more than 90°.
ΔGHI is an

6. obtuse triangle.






B. Triangles can be
classified according
to their sides.
1. Equilateral
Triangle – an
equilateral triangle
has 3 equal sides.
ΔABC is an
equilateral triangle.



2. Isosceles Triangle
– an isosceles triangle
has 2 equal sides. A
triangle in which at
least two sides have
equal measure.
ΔDEF is an isosceles
triangle.



3. Scalene Triangle –

7. a scalene triangle has
no equal side.
ΔGHI is a scalene
triangle.



H. Finding practical application of
concepts and skills in daily living
Allow pupils to name
objects that have a triangle
and a quadrilateral shapes.
Give cutouts of different
triangles. Let them identify
what kind of angles are
they. They can use ruler or
protractor.
Identify the quadrilaterals
and copy them on your
answer sheet.


Identify the quadrilaterals
and copy them on your
answer sheet.



I. Making Generalization and
abstraction about the lesson
What is a polygon?
Describe a triangle and a
quadrilateral.
What are the different
triangles according to sides?
According to angles?

Quadrilateral is a four- sided
polygons.
✓ There are 5 different
types of quadrilaterals
namely.
• Parallelogram is a
quadrilateral with two pairs
of parallel sides and its
opposite sides are equal.
• Rhombus is a
quadrilateral that has 4
equal sides.
• Rectangle is a
quadrilateral with two pairs
of parallel sides and has 4
right angles.
• Square is a quadrilateral
that has 4 equal sides and 4
