Chapter 6 Project: All Things Polygons!
Name: ________________________________________________
This project will enhance your understanding of polygons, how to create polygons, name
polygons, find man-made polygons, natural polygons, and find an application for polygons. This
project is a research project that will require time outside of class looking up necessary
information on the Internet. It will also require that you organize your project and have it finished
and ready to present on:
Due: Friday 2/14
There are 4 parts to the project and a few opportunities for extra credit, if you wish to go the extra
mile . You will have today (1/24) and Thursday 2/13 to work on it in class. Other than those two
days you need to be working on it outside of class. Please do not forget and wait until the last
day – you will not be able to finish it with one day in class.

Part 1: Regular Polygons
In Part 1 you will be required to draw, name, and answer questions based on two regular
polygons given and one of your choice.
A. Use the provide coordinate planes to draw the specified polygon.
B. Use the Internet to find the Greek name for that polygon. (provide name of site)
C. Find the sum of the measures of the interior angles of each polygon.
D. Find the measure of one interior angle of each polygon.
E. Find the measure of one exterior angle of each polygon.
Follow the provided example
6-gon
10-gon
B. Name: ________________________________
B. Name: ________________________________
C. Sum = __________
C. Sum = __________
D. One Interior angle = ___________
D. One Interior angle = ___________
E. One Exterior angle = ___________
E. One Exterior angle = ___________
15-gon
Your Choice: __________
B. Name: ________________________________
B. Name: ________________________________
C. Sum = __________
C. Sum = __________
D. One Interior angle = ___________
D. One Interior angle = ___________
E. One Exterior angle = ___________
E. One Exterior angle = ___________
Bonus (optional):
Choose a Regular Polygon with 20 or more sides.
A. Number of sides: _________________
B. Name: ____________________________________
C. Sum = _________
D. One Interior angle = __________
E. One Exterior angle = __________
Part 2: Man-Made Polygons
In Part 2 you will be required to find images of 12 man-made polygons.
You may either take pictures of man-made polygons or print out images from the Internet. It must
be clear what the man-made object is and you must outline and name the polygon. The
polygons do not need to be regular polygons, but you may not have more than 2 of any one
type of polygon. You must have 12 different images.
Example:
Part 3: Polygons in Nature
In Part 3 you are required to find 4 examples and images of polygons found in nature.
Many plants produce flowers in the shape of a pentagon. Cut open fruits and vegetables to
discover more polygons within their inner structure. The skins or shells of reptiles often repeat in a
polygonal design. For this portion of the project you must either take a picture or find an image of
polygons found in nature. Outline and name the polygon used. Again, you may not use a
polygon more than twice. You must have 4 different images.
Part 4: Flags
In Part 4 use www.flagpedia.net to find 6 flags that contain two or more polygons each. Paste
the images of the flags below and outline and name the polygons used. Also, give the name of
the country that the flag belongs to. Again, you may not use a polygon more than twice. You
must have 6 different flags.
BONUS (Optional): Flexagons
In order to earn extra credit, all directions must be followed and your flexagon created carefully
and neatly.
Go to: www.flexagon.net to find information on flexagons. Use this information to answer the
questions below. Pick one flexagon, print out the template, and create your flexagon through
folding and gluing. Bring your created flexagon into class to show the rest of the class.
1. What is a flexagon? You may need to do some more research in order to answer this question.
2. What are flexagons used for?
3. What is the name of the flexagon that you choose to create?
4. From 1 – 10 (1 being “super easy” and 10 being “impossible”), how hard was it to fold your
flexagon?
