Objectives
Objectives must be met over the week and connected to the curriculum standards. To meet the objectives, necessary procedures must
be followed and if needed, additional lessons, exercises and remedial activities may be done for developing content knowledge and
competencies. These are assessed using Formative Assessment strategies. Valuing objectives support the learning of content and
competencies and enable children to find significance and joy in learning the lessons. Weekly objectives shall be derived from the
curriculum guides
The learner demonstrates understanding of key concept of axiomatic structure of geometry and triangle congruence.
The learner is able to communicate mathematical thinking with coherence and clarity in formulating, investigating, analyzing, and
solving real-life problems involving congruent triangles using appropriate and accurate representations
Content is what the lesson is all about. It pertains to the subject matter that the teacher aims to teach. In the CG, the content can be
tackled in a week or two.
The learner illustrates the SAS, ASA and SSS
congruence postulates. (M8GE-IIId-e-1)
The learner illustrates triangle congruence.
(M8GE-IIId-1)
a. Name the corresponding parts of two
corresponding triangles.
Show that two triangles are corresponding by illustration.
a. Name corresponding parts of two corresponding
triangles.
b. Illustrate the SAS congruence postulate
Identify the included side and included angle in a given
triangle

“Supportive-CongruentTriangles”Activity
Two triangles are congruent if
their vertices can be paired
so their corresponding sides
are congruent and
corresponding angles are
congruent.

SAS Congruence
Postulate
If two sides and the included
angle of one triangle are
congruent to the
corresponding two sides and
the included angle of another
triangle, then the two
triangles are congruent.
ASA Congruence
Postulate
If two angles and the
included side of one triangle
are congruent to the
corresponding two angles
and the included side of
another triangle, then the
two triangles are congruent.
