Group Title
Observe parallelogram ABCD plotted on the coordinate plane below.
Part I: Provide the coordinates of a parallelogram A’B’C’D’ that is congruent to parallelogram ABCD. Explain why these figures are congruent. (4 points)
Part II: Provide the coordinates of a parallelogram A’’B’’C’’D’’ that is similar to parallelogram ABCD. Explain why these figures are similar. (6 points)

Yeah. Coordinate Geometry.

Do you know what a Dilation and Translation is?
 one year ago

rajfk35 Group TitleBest ResponseYou've already chosen the best response.0
translation is it when you move the figure to the opposite side from where it is

And what about a dilation, rajfk?

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Translation isn't the opposite side one. Isn't reflection the one that you described?

It's when the figure gets bigger or smaller by a certain factor.
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
So anyway, translation is when you add random numbers to both x and y. An example of that would be (x,y)> (x+1,y+3)
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Dilation is when something gets smaller or bigger by a constant like Darlin said. An example, if the constant is 2 would be (x,y)>(2x,2y)

So for the first part, translations make geometric objects stay congruent
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Because the distances are all still the same

So you find the coordinates for all 4 points and add or subtract whatever you want to them to get the first part

Shift all the points one column to the right if you're feeling lazy

For the second part, what you want to do is get the coordinates and multiply x and y by 2. Then you plot the new coordinates you found

Lazy doesn't get u anywhere.... I know that from experience, but it can work. Just make sure you double check your work...
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Lazy gets you somewhere if you're good at it. But that's just for math. I fell asleep for the math placement test and got double period algebra. But I got an 100 average for it

raj. How are you holding up?

Can't you do a proportion for the second part to see that they are similar?
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Well, yeah. But that's just for checking it. You would be guessing and checking to get the coordinates
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
okay. Raj. Give me the coordinates for point A I'm too lazy to find it
 one year ago

DarlingDare Group TitleBest ResponseYou've already chosen the best response.0
hmm... good to know... then I have been doing that part wrong for a long time.....
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Alright. You're taking too long to find it for me. so A is (7,3). What you do is make up a random constant like 2. So (x,y)>(2x,2y), right?
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
So then you plug x and y in to get (2[7],2[3]) or (14,6)
 one year ago

Grazes Group TitleBest ResponseYou've already chosen the best response.1
Which means that A11 is (14,6). Understand?

DarlingDare Group TitleBest ResponseYou've already chosen the best response.0
Well, I understood, but I don't know if Raj did...
