Postulates, t
heorems, and definitions ….Oh MY!!!
Materials needed:
3

pronged folder (pockets optional)
notebook paper OR computer paper
pen OR pencil OR computer
maybe colored pencils, crayons, and markers
Work to be done:
Create a list of all postulate
s, theorems and definitions studied so far in
geometry
along with an example for each
. This should include each one
listed in the book and/or your notes from chapters 1

5 and 10.
Hint: a list of the postulates can be found on pg 706, a list of theorem
s
divided by chapter can be found on pages 707

710, and a list of words that
should be defined can be found
on the back of this page.
How it will be graded:
In a folder with a cover sheet
–
20 points

When it is due:
Wednesday, January 21, 2009 at the beginning of your assigned class period.
Why we are doing this:
This project will help you l
earn the postulates, theorems and definitions we
have covered since the beginning of the year. We will add to the project
throughout the remainder of the year as we learn more and more about the
study of geometry. You will be able to use your folder as a
reference tool
while doing classwork, homework, and possibly even quizzes and tests.
