If useful, describe an activity how you
can use it
This can be used to get the students
recognize the use of Cartesian coordinate
plane in plotting points and identifying the
points and its coordinates on it.
This can be used to illustrate that the
sum of the angles of triangle is 1800.
This can be used to prove and
strengthen that the theorem really works
in all right triangles.
This can be used as an application of
the formula in getting and showing the
distance or length of two points in a
coordinate plane.
This can be used to show how angle
bisector be constructed and also to
strengthen the students’ knowledge on
Angle Bisector.
This can be used as an illustration in
proving the ASA Triangle Congruence
Theorem
This can be used as an illustration in
proving the HyL Right Triangle
Congruence Theorem
This can be used as an illustration in
proving the SAS Triangle Congruence
Theorem
This can be used as an illustration in
proving that

LESSON PLAN
SUBJECT: Mathematics
TOPIC: Geometry
TITLE: Congruent Triangles Theorem (SSS)
LEVEL OF STUDENTS: Third Year Secondary level
TIME REQUIRED: 50 minutes
KNOWLEDGE REQUIRED BEFORE THIS LESSON:
1. Properties of Real Numbers
2. Definition of Congruent Triangles
OBJECTIVES
Students at the end of the lesson will be able to:
a. state the equivalence relation for segments and angles,
b. use SSS Congruence Postulate to show triangle congruence, and
c. develop cooperation among the group and use time wisely in doing the task.

2.Symmetric Property:
If a = b, then b = a
3.Transitive Property:
If a = b, and b = c,
then a = c
b. Reviews the definition of b. Students must be able to give
congruent triangles. Place two

other triangle.
Assessment
And follow-up.
Asks the students to bring out
Let the students answer the
and open their reference book on a exercises given on the Geometry
certain page that will surely help Workbook
the students understand further the
lesson.
Worksheet:
Directions: Work as a group cooperatively. Do the worksheet as indicated.
1. Draw Triangle TUE on a piece of paper.
2. On another sheet, draw Triangle WED such that TU ≡ WE, UE ≡ ED and TE ≡ WD.
3. Using a sheet of patty paper trace ∟W, ∟E, ∟D; and put ∟W over ∟M; ∟E over
∟O, and ∟D over ∟N. What relationship can you give between the pair of angles?
4. Cut the triangular regions and compare by placing WED upon MON. What have you
noticed? List down all the observations you make.
5. Give conclusion about the relationship between two given triangles.
