Polygon Sum Theorem

# 6.1

• READ pg. 280
• perform Investigation 6.1 to get the answers to the following 2 conjectures:
• C-38 Quadrilateral Sum Conjecture: The sum of the measures of the four angles of every quadrilateral is -?-
• C-39 Polygon Sum Conjecture: The sum of the measures of the n angles of an n-gon is -?-
• (1-14) all
• (16-19) all

Post your conjectures on the blog first. Once you've got 10 other people who agree with your conjectures, then you can attempt problems 1-14 and 16-19.

Let's make things interesting..... awwwwwwwwwwwww yeah!.......

In light of all the long faces after today's test, I am offering up some extra credit tonight. Read on for further details.....

There is a total of 18 problems for homework this evening. I am giving an extra credit 5 points to the student who posts the correct solution AND explanation of said solution of each problem. Once the correct solution/explanation has been posted for that problem, the extra credit has been gobbled up. Move onto the next available question. That means first come, first serve. Stipulations:

1. you can only receive a maximum of 5 extra credit points tonight. that means if you post a correct solution/explanation for #1, you can't receive extra credit for #2 also. No need to be greedy! Sharing is caring!
2. you can't begin posting a solution/explanation for extra credit until 10 people post that they agree with your conjectures
3. be careful.... if you post an incorrect solution/explanation, I will take 5 points away from your grade. Let me know that you want me to consider your answer for extra credit by posting the words"FINAL ANSWER" at the beginning of your posting. Otherwise, I will assume that you are asking a question and do not want to be penalized for a wrong answer.
4. Remember to type your name and period at the end of your post.

Good Luck! May the best 18 people win the available extra credit points tonight!
