variety of strategies.
LEARNING COMPETENCY CODE
The learner states and explains the Midline Theorem, solves related problems, and M9GE-IIId-1
appreciates its practical application in real life.
I. OBJECTIVES: At the end of the lesson, learners are expected to:
Knowledge states and explain Midline Theorem
Skills solve problems applying the Midline Theorem in triangles
Attitude shows appreciation for the practical applications of mathematics by demonstrating
teamwork and perseverance.
Values appreciate the importance of using midline theorem in real life situations.
The Midline Theorem: The segment joining the midpoints of two sides of a
II. CONTENT
triangle is parallel to and half the length of the third side.

Start the lesson with a scenario related to midline theorem:
Aling Mids owns a triangular farm. Two sides of the farm are extended, and the
new lengths are double the original sides. If the original measurements are 8m,
10m, and 12m, what is the new perimeter of the farm?
Ask students to estimate or brainstorm how doubling sides can impact the shape
and size of the farm. This aims to create excitement and curiosity about the
upcoming lesson.
B. Activity/ Engage students in a group activity where they are given a chance to collaborate
Strategy with others.
Divide students into small groups and provide them with a triangle diagram. Ask
them to locate midpoints and draw the segment connecting them.
Have students predict relationships between this segment and the third side of
