This Blog exists for the collective benefit of all geometry students. All questions are welcome. The more specific your question (including your own attempts to answer it) the better.
EVEN MORE WELCOME ARE ANSWERS FROM FELLOW STUDENTS. BLOG ON!
There will be a question very much like this on the quiz. If someone answers, I'll chime in later and confirm the response. Include a brief explanation of each answer so as to help your classmates.
Q. What can you conclude by using the given statement together with each of the following statements? If no conclusion is possible, write none:
Schmos have no antlers.
1, Max has antlers. 2. Natasha is a schmo. 3. Jordan has no antlers. 4. Drew is not a schmo. 5. How could you have re-stated the original as a conditional (with an "if-then")?
(Hint: In a statement like the one above, there is as implied "All" in front of the word Schmo)
Well, you are kinda right, in that you are saying #3 & #4 are inconclusive. The way the question was phrased, it was looking for you to say "none" for 3&4... since I'm only a semi-nasty teacher (with no antlers), I would have marked your answer correct based on how you phrased it.
but we all know that i am a schmo, so jordan's theory must be false. oh ya, um pg 222 number 5. just give me the setup, it seems clear as to how to find the third length although im not sure how i should start or what the conclusion should look like. as in should it be "if a=1 and b=2 then c should = whatever." or "c where c=a/b" like that.
Well, look back to how the min and max values for the third side were calculated in problems #1-3.
What did you do with the two given side length values in order to find the third?
Let's look at #1. Hopefully, after yesterday's classroom exercises, you can see how the problem is done visually. Mathematically/algebraically, you simply subtract the smaller from the larger to find the "border value" for the shortest possible third side, and you simply add the two sides to find the "border value" for the longest possible third side.
In problem #5, you are being asked for a "simple" formula in terms of a & b. Given that a > b, what math do you have to perform to find the border values?
If it is still not clear, we will discuss in class.
I assume you mean from "Test 22" (which was a quiz). As much as I hate trick questions... I guess that was a trick question.
A correct statement would be: The first step of an indirect proof is to ALWAYS assume temporarily that the conclusion is not true.
In question #18, the quiz-makers deviously substituted the word "hypothesis" for "conclusion" thus rendering a correct answer of NEVER... that wasn't very nice, was it?

1)MAX IS NOT A SCHMO
ReplyDelete2)NATASHA HAS NO ANTLERS
3)JORDAN CAN BE A SCHMO
4)DREW MIGHT HAVE NATLERS
5)IF SOMEONE IS A SCHMO THAN THEY HAVE NO ANTLERS
I agree with jordan.

#11 is weird
ReplyDeleteand i agree with nick
for #11, hint can an external angle help?
ReplyDeleteok, so i think that i have it now. the only question i have is, on # 18 in the test... The answer is sometimes, correct?
