This is an interactive presentation to catch the attention of learners.

2. Visualizes, names, describes and draws
polygons with 5 or more sides.
Describes and compares properties of
polygons, regular and irregular polygons.
Visualizes the congruent polygons.
LEARNING OBJECTIVES

3. POLYGON
They are closed plane figure formed by line
segments that meet at a common point.
These line segments also known as sides
meet at a common point which is called
vertex.

4. side
vertex
angle

5. TYPES OF POLYGON
A polygon that has all
equal sides and angles.
REGULAR
POLYGON
IRREGULAR
POLYGON
A polygon that has
unequal sides and angles.

6. CLASSIFICATION OF POLYGON ACCORDING TO NUMBER
OF SIDES
Number of Sides Name of Polygon
3 Triangle
4 Quadrilateral
5 Pentagon
6 Hexagon
7 Heptagon
8 Octagon
9 Nonagon
10 Decagon
n n-gon

7. CONGRUENT POLYGONS
They are comparison of two alike polygons
with corresponding sides and angles. To
illustrate congruency, it is represented by
the symbol which means “congruent to”.
