Inequalities in One Triangle

Answer 1

This site it not to be used for "swapping answers".

It is better to guide the user to an answer rather than doing all the work yourself.

We discourage giving out answers without letting the asker at least take some part in the analysis - the aim of this site is to teach.

Please refer to our code of conduct at http://openstudy.com/code-of-conduct for more information. Thank you.

Answer 2

Im fully aware of the protocol. Reason why I am pleading is because I have NO CLUE at all on what to do. If you can help me get to the answer it would be greatly appreciated.

Answer 3

post the answers, one at a time (or some people like to post different questions into different subtopics) and we will be able to see how much help we can offer you :)

Answer 4

post the questions that is ....

Answer 5

your link just presupposes that we should log into your site and do the work for you ...

asking the questions themselves would be more suitable to us

Answer 6

well administrators are just not cool.

anyway, primary, i cant give a question out because I have no idea whats going on. The assignment is pretty much a riddle. Make a triangle with a short A side, a long B side and I have to figure out what side C measures.

see, thats why i posted the assignment online. theres really no way of asking a direct question without know what that question is.

Answer 7

is it a right triangle? or are you being asked what the range of values c would have to be for it to make a triangle in general?

Answer 8

"range of values c would have to be for it to make a triangle in general?"
on my paper, i have a chart with the following under one column.
>Possible Length for a third Side(c).
>impossible Length for a third side (c).
>inequalities for a third side of length c.

Im suppose to come up with the measurements for side A and B and then figure possible measurements for side C.

I guess side A is 5 inches and side B is 13 inches. Now how can i find side C?

Answer 9

well, a property of triangles is such that the 2 smaller legs have to add up to bigger than the largest leg

it sounds like A and C are the small legs and B is the large one

therefore

A + C > B has to be satisfied

Answer 10

yes side B is the longest one.

so, if im doing this right.
A(5) + C(?) > B(13)
C = anywhere from 1 to 7

Answer 11

5 + C > 13

C > 8, but has to be less than 13 so that it doesnt become the large side :)

Answer 12

thank you. it now seems easier than before.
does this rule go with any triangle with side B the longest?


another problem is...
What does "inequalities for a third side of c" mean?

Answer 13

the term "inequality" just means that the solution set is not necessarily a single answer, but can have a range of values

Answer 14

the rule fits for any triangle

short1 + short2 has to be greather than long

notice that if the shorts are too short, we cant connect their ends to form a triangle

Answer 15

okay. im starting to mentally picture this. But if the two sides were equal side B, wouldnt it become a line?

example. from 5 + C = 13, wouldnt c<8 include the number 8 as a possible choice?

Answer 16

yes, if the 2 shorts equal B then its just a line, and not a triangle, therefore the need to add up to larger than B :)

Answer 17

5+C > 13 is the needed condition, with the condition that C < B .. cant have a short side longer than the longest side can we?

5+C > 13
-5 -5
-----------
C < 8

there fore the range for C is between 8 and 13

Answer 18

now that makes sense. you pretty much summed it all up.

bonus question. can u give me an example of an inequality of a triangle?

Answer 19

this might help, pretty much says that the sum of any 2 sides has to be bigger than the 3rd side to work a triangle

http://www.regentsprep.org/Regents/math/geometry/GP7/LTriIneq.htm

not real sure what an example of an inequality of a triangle would look like :/

Answer 20

okay i think i got it. If i dont i can get the minus points. I just need to advance forward but as my teacher says, quality over quantity. Thanks armistre. You have helped me enough.

Answer 21

good luck :)
