I just need help with this whole thing... I need explanation not just answers.
Where are the vertices of the parallelogram listed?
oh my bad...here's the graph and the vertices.
Each side of the parallelogram has two coordinate points associated it. Do you know the formula y=mx+b?
yea thts the slope-intercept form.
I commend you! This is the best question I've seen in OS in a very, very long time!
Yep so if we looked at the side AB where A(0,3) and B(3,0) would you know how to calculate the slope m?
lol thnk you? @across
yea nd i have those in already in the beginning of the assignment.
Oh...ok that makes sense. So you are needing help on part b?
yea i need help on part b and c....also for question 2 prt b and c.
ok check this attachment...do you know the pythagorean formula?
yea a2+b2=c2 right?
Yes, so when we look at the side AB that is actually the hypotenuse of our triangle. Do you understand how I made that triangle?
okay so then wuld we do the special right triangle formula?
Well if you mean the pythagorean formula; then yes.
yea thts wat i meant. so then it will be 18?
Well remember the "c" in the formula is squared so you have to take the square root of that.
It's like 4.24.... sumthin sumthin
Yep
so wat does this have to do with the assignment?
here's another visual
well part b was finding the length of the sides, and that is what you have just found
okay so now i just use the Pythagorean theorem nd it'll give me my lengths?
yes, but if you look a picture of the parallelogram you will notice all the sides are the same
the diagonal lengths can be found by inspection, but it usually doesn't work out that way
okay so let me see if i got this.... all of part b answers is 4.24...?
No, all of the exterior sides are that answer. The diagonals are a different length.
okay so how do we figure out the lengths.
look at this picture...the blue lines are the diagonal lengths.
okay...
How long are those lines?
3?
No, count how my squares on the graph are between A and C
4?
if ur countin the halfs 5?
oh ohld on is it 7?
wait is it 9?
Yeah it's 9
Acutally, hold on...I think it's 71
71! how did u get tht?
It's 6 dude.
C. the parallelogram is a square D. the perimeter is four times the length of the sides E. Area is 18
oh okay..r u gettin mad at me?
Oh no...i would never. I just feel like your not taking the time to look at the picture.
i did it's just i dnt get the whole proofs thing it's very hard to me idk why it's like i get every thing else but this is my weakness
Ok so are you seeing generally where I got the diagonal lengths from? Or do you need a better example?
is tht an o or a d?
srry... that is an "o" for origin
I think i get it but if u wuldn't mind i culd use one more example. it's aight man
u know wat i think i got it u dnt need to give me another example...man thnks a lot u reallly helped me understand it better
alright find the length of the side AB of the parallelogram
remember....make a right triangle with the side you are trying to find as the hypotenuse
yea nd i did tht so now i have to use the pt?
yep
so is this how the triangle wuld look?
