C. Presenting Examples/ instances of
the new lesson
What is trapezoid?
The trapezoid is another type of
quadrilateral that is equally
important as a parallelogram.
D.
Discussion of the lesson
through illustrative
examples. (Proving)
Discussion of the lesson through
an illustrative example with
explanation,
Discussing new concepts and
practicing new skills no.1.
The segment that joins the
midpoints of a trapezoid's legs is
called the median.
The Midsegment Theorem of
Trapezoid
Theorem 2: The median of a
trapezoid is parallel to each base
and its length is one half the sum of
the lengths of the bases.
E. Discussing new concepts and
practicing new skills no.2
Activity A
Questions:
• Does EF̅̅̅̅̅̅̅̅ look parallel to the
trapezoid’s base?
• Measure EF̅̅̅̅̅̅̅̅ using your ruler.
How long is it?
• What is the sum of the bases of
trapezoid ABCD?
• Compare the sum of the bases
and the length of EF̅̅̅̅̅̅̅̅ . What did
you find?
Activity B
Questions:
• What two pairs of angles formed
are base angles?
• Compare the measures of the
angles in each pair. What did you
find?
Illustrative Examples
Analysis

F. Developing Mastery (Leads to
Formative Assessment 3.)
What is Midline Theorem?
Midline Theorem
Theorem 1: The segment joining
the midpoints of a triangle's two
sides is parallel to the third side
and half as long.
TRAP is an isosceles
trapezoid with median
.
Determine the relation
exists between each of the
following:
G. Finding practical application of
concepts and skills in daily living
A lot of kids love to play on
the different rides and one of
it
is
the
swing.
Activity 5.
TRIAD
Let the learners go outside the
classroom and look for at least three
objects or structures with trapezoidal
shape. Let them prove it using the
measurement of its sides and
angles.
Many different kinds of
ornamental/ medicinal
plants are found in
Tagaytay because of its
good climate. Restaurants
like Sonya’s Garden is
popular for their fresh and
organic dishes, considering
this pot of fresh flowers.
Find HR.
Given: MARI is a kite with
diagonals
and
complete
the following:
Given: JKLM is a kite with
and
Prove: ∠K
∠M
It is ________ that
and
. By the ________
Property ≌ . This means that
ΔJKL ≌ ΔJML by ________ So
∠K ≌∠M by ________.
H. Making Generalization and
abstraction about the lesson
A midline of a triangle is parallel
to a side of the triangle and its
length is half the length of that
side.
The Mid segment Theorem
The median of a trapezoid is
parallel to each base and its length
is one half the sum of the lengths of
the bases.
Things to remember:
1. Base angles of an
isosceles trapezoid are
congruent.
2. Diagonals of an
isosceles trapezoid are
3.
The median of a
trapezoid is parallel to
the base and its length
is half the sum of the
lengths of the bases.
The median of a trapezoid
bisects each of the
diagonals.
Things to remember
1. The diagonals of a kite are ⊥.
2. Exactly one pair of opposite
∠s is ≌.
3. Exactly one diagonal of a
kite bisects a pair of
opposite ∠s.
