The document defines polygons as plane figures with three or more line segments that are joined at their endpoints. It discusses the characteristics of polygons, including the minimum number of sides, regular vs. irregular polygons, and provides examples of common polygon types up to decagons. The lesson expects students to define polygons, identify different polygon types by number of sides and angles, and participate in class discussions at a 95% mastery level.

1. POLYGONS
The word polygon is a
Greek word. POLY
means many and GON
means angles

2. The following are not polygons.

3. The followings are polygons

4. At the end of the lesson you are expected to:
 Define Polygons;
 Identify the different kinds of Polygon
according to the number of sides and
number of angles;
 Actively participate in the class discussion
with 95% mastery level.

5. What have you notice in
the given groups of
polygons?
They are close figure
What have you
notice on their side?
Their side is made up of
line segments joined at
their endpoints.

6. have you notice, how many
minimum number of line
segment does a polygons have?
There are three or
more line segments.
Define polygons?

7. Polygons are close figure
made up of three or more
line segments joined at their
endpoint.

8. Can we consider this a polygon?

9. Always remember that a
polygons that having equal angle
is called regular polygon, and to
those who have not is called
Irregular polygons.

10. What is a polygon?
A polygon is a close plane figure made up of three
or more line segment joined at their endpoints.
What were the different types of polygon that
we already discuss?
Triangle, quadrilateral, pentagon, hexagon,
heptagon, octagon, nonagon and decagon.

11. Bring out a ruler, and answer sheet, then
draw the following regular polygon inside
each box.
1. A regular polygon with 3 sides.
2. A regular polygon with 4 sides.
3. A regular polygon with 6 sides.
4. A regular polygon with 5 sides.
