B. Establishing a purpose for the lesson
Today, we are going to take a closer look at quadrilaterals. Look around you did you see any shapes that can be called a quadrilateral?
Indeed! Very Good! As we procees to our proper discussion. Let me share with you first our lesson objectives to attain this session.
LESSON OBJECTIVES The students will be able to:
- Classify quadrilaterals
- Identify properties of quadrilaterals including angle measurements of quadrilaterals.

Questions: Possible answers!
- What have observe in the figures? 1. It is a rectangle, square,
- What makes them special quadrilaterals? trapezoid, rhombus and
parallelogram.
- Different shapes do differ from each other in terms of sides or angles. May shapes have 4 sides but the difference in angles on their Very Good! sides makes them unique. Ans that we call these 4-sided shapes the As you have noticed that Quadrilaterals can quadrilaterals. be seen in everywhere around you..
D. Discussing new concepts and practicing new skills # 1
Given the previous activity, you have learned the figures of a quadrilaterals? In this topic, you will get an idea about the quadrilaterals together with the properties.
QUADRILATERALS
In Euclidean geometry, a quadrilateral is a four-sided 2D figure whose sum of internal angles is 360°. The word quadrilateral is derived from two Latin words ‘quadri’ and ‘latus’ meaning four and side respectively. Therefore, identifying the properties of quadrilaterals is important when trying to distinguish them from other polygons.
Properties of Square
Square formula area and perimeter of a square If the side of a square is ‘a’ then,
- Area of the square = a × a = a²
- Perimeter of the square = 2 × (a + a) = 4a
QUESTION! Is a square a RECTANGLE? Is a rectangle a SQUARE?
Very Good! So, lets proceed to
trapezoid. TRAPEZOID
A trapezoid is a quadrilateral that has only one pair of parallel sides. The parallel sides are referred to as ‘bases’ and the other two sides are called ‘legs’ or lateral sides.
A trapezoid is a quadrilateral in which the following one property:
Trapezium formulas area and perimeter of a trapezium If the height of a trapezium is ‘h’ (as shown in the above diagram) then:
1 of the trapezium= Sum of lengths of all the sides = AB + BC + CD + DA 2 of the trapezium = ½ × (Sum of lengths of parallel sides) × h = ½ × (AB + CD) × h
RHOMBUS
Possible answer! A SQUARE can be also called a rectangle because it has four right angles ans its opposite sides are equal and parallel. But a RECTANGLE is NOT a square because it does not have equal sides.
A rhombus is a quadrilateral whose all four sides are equal in length and opposite sides are parallel to each other. However, the
In a quadrilateral ABCD, ∠A = 72° and ∠C is the supplementary of ∠A. The other two angles are 2x–10 and x + 4. Find the value of x and the measure of all the angles. Solution : <A+<C= 72+<C= <C=180- <C=
B+<D= 2x-10+x+4= 3x-6= 3x = 3 3 x=
Did you get it class?
Answers may vary.
E. Discussing new concepts and practicing new skills # 2
Since you understand so let us have an activity. I wil give you 5 mins to answer and then end your answers to our google classroom for me check and record your scores. Your participation will ne graded also.
Activity 1 1: m<A= 3x+ m<B= 5x+ m<C= 3x m<D=2x+ Find m<D M<D
- ABCD is a rectangle whose diagonals AC and BD intersect at O. If <OAB=46°, find <OBC.
Are you done class? So, let us see if you got the correct answer so lets answer.
Possible answers:
F. Developing mastery (leads to Formative Assessment)
And this time, let us see if all of you
really understands the discussions. Let
us have a quiz and apply what you
have learned in our discussion.
You are going to answer as to what
types of quadrilateral is being describe
and im every question you are given 10
seconds to answer in our chat box. Am I
Clear?
Yes ma'am.
Activity 2: What am I!
1. I only have one pair of sides
that parallel. What Am I?
2. My opposite angle are equal, all
sides are equal, opposite sides are
parallel. Lastly, my diagonals bisect
each other and perpendicularly. What
Am I?
3. All my angles are equal, opposite
sides are equal and parallel and my
diagonals bisects each other. What Am
I?.
4. Opposite angles are equal,
opposite sides are equal and parallel
the diagonals bisect each other.
Adjacent angles are equal to 180°.
What Am I?
5. All my angles are equal to 90°,
all sides are equal and parallel and
diagonals bisect each other
perpendicularly. What Am I?
Possible Answers: 1. TRAPEZOID 2. RHOMBUS 3. RECTANGLE 4. PARALLELOGRAM 5. SQUARE
Very Good class!
Congratulations, Everyone!
G. Finding practical application of concepts and skills in daily living
Problem solving that involves quadrilaterals that can be applied im daily living.
Possible answer.
PROBLEM:
Adam wants to build a fence around his rectangular garden of length 10 meters and width 15 meters. How many meters of fence he should buy to fence the entire garden?
A desktop in the shape of a parallelogram has a base of 30 inches and a height of 40 inches. What is the area of the desktop?
Solution Step 1: Given
Adam has a rectangular garden. It has a length of 10 meters and a width of 15 meters. He wants to build a fence around it. Step 2: To find
The length required to build the fence around the entire garden. Step 3: Approach and Working out
The fence can only be built around the outside sides of the garden.
So, the total length of the fence
Let us answer the given problem.
required= Sum of lengths of all the sides of the garden. Since the garden is rectangular, the sum of the length of all the sides is nothing but the perimeter of the garden. Perimeter = 2 × (10 + 15) = 50 metres Hence, the required length of the fence is 50 meters.
Very well, class!
Give yourselves a big virtual clap!
- Area of parallelogram A=lxh l=30in h=40in A=30inx40in A=1200in
Students do as told.
H. Making generalizations and abstractions about the lesson
Let us have a short review with regards to our topic. Possible answers: QUESTIONS!!!
- What is a Quadrilateral?
- What are the two properties of Quadrilateral?
- What are the special types of Quadrilateral?
- If the interior angles of a quadrilateral add up to 360°. What much each interior angle of a square be?.
Thank you so much! You are great students!.
- quadrilateral is a four-sided 2D figure whose sum of internal angles is 360°. The word quadrilateral is derived from two Latin words ‘quadri’ and ‘latus’ meaning four and side respectively. 2 properties are
- A quadrilateral should be closed shape with 4 sides
- All the internal angles of a quadrilateral sum up to 360°. 3, square, trapezoid, rhombus and parallelogram.
- Each angle is a right angle of 90°. I. Evaluating learning Let us have this time our final activity. You are given 10 minutes to answer.
Activity 3: Compute me!
Possible answers:
1.
- The angles of a quadrilateral are in the ratio 2:4:5:7. Find all the angles.
Very Good class!

Out of 28 student's I Can say that more than average who got earned 80% in the evaluation.
B. No. of learners who require additional activities for remediation who scored below 80%
More or less 10 students requires additional activities for remediation who score below 80%.
C. Did the remedial lessons work? No. of learners who have caught up with the lesson
Establishing remedial lesson really works a lot to students with low scores since remedial will help them to be better.
D. No. of learners who continue to require remediation
Not less than 5 students requires continue remediatiom and more attention.
E. Which of my teaching strategies worked well? Why did these work?
For me, the strategies that works well is the way I Let tjem interact in the virtual class and that letting them do make critical thinking skills. And that is one way that it will work will. F. What difficulties did I encounter which my principal or supervisor can help me solve?
In terms of the internet connection because that is the common problem we are facing now. That maybe my supervisor can help me.
G. What innovation or localized materials did I use/discover which I wish to share with other teachers?
The virtual presentation which as of now is in great use because of the andemic we are facing now. Interactive visualization to the learners.
