definition q's, measuring angles w/ protractor, etc

[Shiznits]

I have this question of a hmwrk problem and i cant seem to find the answer to:

1. When You Use _? Reasoning you are generalizing from careful obsevation that something is probably true. When you use _? Reasoning you are establishing that, if a set of properties is accepted as true, something else must be true.

Now for the first ? i wanna say visual reasoning but im not sure, and for the second one maybe equation reasoning... i wish i payed attention in class.

Also this problem:

4. Triangle DGT is isosceles with TD = DG. if the perimeter if Triangle DGT is 756 cm and GT = 420 cm, Then DG =?What type of reasoning do you use, inductive or deductive reasoning, when solving this problem?

now i kno how to do the prlbem in degrees because its 180 for any triangle... but i have no idea what to do for cm.. now i dont know why our teacher did not teached us this. she gives us random hmwrk and i dont like that.

yea i need help with these 2 i can pretty much do the other ones in my own.

but i dont really get this:

5. The sum of the measures of the five marked angles in stars A through C is shown below each star. Use your protractor ro carefully measure the five marked angles in Star D.

So the written pic is:

A. Star <--- book has a star pic. 180Degrees
B. Star 180 Degreees
C.Star 180 degrees
D.Bigger Star...

all stars are differently shaped stars but isnt obvious that D is also 180 degrees of all the angles it has?

1) Yes, it would have been better if you'd "payed" attention in class, since this exercise is meant to be nothing more than a simple application of the definitions that you are expected to "kno".

To find the definitions, try looking in the relevant section of your text, or look up "reasoning" in the index. If you "cant" find the answer there, try doing an online search for appropriate keywords, such as "reasoning", "generalize", "properties", and such. You might also try looking up the definitions of the types of "reasoning" listed in the other exercises you posted.

4) What is the definition of "perimeter"? (Hint: It has nothing to do with angle measures.) What is the definition of "isosceles"? (If you didn't pay attention in class when your instructor "teached" this, try using a dictionary.)

5) Since we "cant" see the picture you're looking at, there "isnt" any way for us to evaluate the exercise. But the instructions are simple enough. Grab your protractor and measure the marked angles.

ya thx. i like your way of explaining things... u use questions that get me to the answer by myself without u giving me the answer. and ill have diff questions in the future. maybe later ill have some. but thx for the help.
