Mr. Maki
Math Project
Due
Write Your Own Textbook!!
For this project, you will be constructing your own textbook for Chapter 8. Your job is to
create your own mini-textbook about the topic SSS, SAS, ASA, AAS, HL Theorem, and
CPCTC. You may use your textbook, notes, quizzes, homework, and your own knowledge to
build your textbook. Your textbook should include words, drawings, images, magazine cut
outs and anything that you can think of that relates to the topics. Use your minds and please
be as creative as you can and want to be! Remember, you are trying to sell your textbook to
schools, teachers and students. Below is a checklist of what you need to include.
 A cover page with your topic title and your name
 Explain SSS, SAS, ASA, AAS, HL Theorem, and CPCTC with diagrams.
 Provide 1 example and show a two-column proof which uses SSS or SAS.
 Provide 1 example and show a two-column proof which uses ASA, or AAS.
 Provide 1 example and show a two-column proof which uses HL theorem.
 Provide 1 example and show a two-column proof which uses CPCTC.
 Each example needs to be taken from the list on the next page.
 When you show each two column proof make sure you explain each step.
Keep in mind that you are writing a textbook. You need to explain
everything!!
 Your last section should explain why schools, teachers and students
should use your book instead of another book.
Here are the example problems you can use for the Textbook Project! You need to use
either example A or B for EACH category.
