This document discusses polygons and contains the following information: 1. It defines what a polygon is and lists some of its key characteristics like being a closed figure formed by three or more line segments. 2. It provides examples of different types of polygons classified by the number of sides like triangles, quadrilaterals, pentagons, etc. 3. It asks the reader to identify polygons in examples and classify shapes as convex or concave polygons.

4.  Comes from 2 Greek words poly (many) and
gon (sides).
 It is a closed figure formed by joining three or
more line segments that meet only at their
end point.
 The segments are called the sides of the
polygon; each endpoint are called vertex.
 Name the polygon using the letters of the
vertices written in order of consecutive
vertices

6. Yes, because it is a closed figure.

7. No, because it has no sides.

8. A. Regular Polygon- These are polygons whose
sides and angles are equal.

9. B. Irregular Polygon-These are polygons with
unequal sides and angles.

10. C. Convex Polygon- These are polygons where
its diagonals lie entirely inside of it.

11. D. Concave Polygon- These are polygons
where some of its diagonals lie outside of it.

12. Number of Sides Name
3 Triangle (tri=three)
4 Quadrilateral (quadri=four)
5 Pentagon (penta=five)
6 Hexagon (hexa=six)
7 Heptagon (hepta=seven)
8 Octagon (octa=eight)
9 Nonagon (nona=nine)
10 Decagon (deca=ten)
11 Undecagon (un+deca=eleven)
12 Dodecagon (duo+deca=twelve)
N-sides N- gon

13. Can you give concrete
examples of polygons
around you?
Identify the name of that
polygon.

14.  Directions: Eddie is looking for some of the
things in his shop and identify it whether it is
a polygon or not.
If it is a polygon you CLAP YOUR HANDS.
If it is not a polygon you STAMP YOUR FEET.

18. Based on the classification of
polygons according to the
number of sides, think two
words that begin with any of
these prefixes (tri, quad,
penta, hexa, hepta, octa,
nona and deca). Define each
word then use it in a
sentence.

19. Triage-the sorting of patients according to
the urgency of their need for care
Nurses do triage in the emergency room.
Pentameter-a line of verse consisting of five
metrical feet

instance that the regularity of a
polygon is being observed or
used.
