Question

Hey babes! One more problem I need help on, thanks sooo much! xx

Answer 1

Why don't you start with a sketch?

Answer 2

Because Im a little lazy right now (; lol

Answer 3

@telliott99 Okay I sketched it out and I am so confused

Answer 4

back

Answer 5

yaay :)

Answer 6

So.. the problem says that the second trapezoid is similar to the first one, it'll have the same ratio of sides, same angles, but a different size.

Answer 7

OK/

Answer 8

okay

Answer 9

The length of the segment PQ is ?
The length of the segment UV is ?

Answer 10

P- (-5,7) Q-(-2,7)
U- (-2,-1) V-(7,-1)

Answer 11

I wonder if you sketched? :)
Anyway PQ is horizontal, its length is the difference is x-values which is 3

Answer 12

I did sketch, I swear! :)

Answer 13

So what is the length UV?

Answer 14

I dunnno. I really suck at this stuff

Answer 15

If you sketch it, you will see that the length UV is 9.
So the second trapezoid is bigger by that ratio of 9/3 = 3.
That's all you get for now.

Answer 16

Here what I did...

Answer 17

@telliott99 look what i attached please

Answer 18

back

Answer 19

go look at my other post

Answer 20

I saw the figure, it looks great!

Answer 21

Now, in the problem the points are U and V, they are labeled E and F on your figure, OK?

Answer 22

yeah i know thats because of the program

Answer 23

No problem

Answer 24

So I think you can count on the x-axis and see that the distance from E to F (or U to V) is equal to 9. Yes?

Answer 25

Now the problem says that UVWX is going to be just like PQRS only maybe a different total size. But it'll be what they call in geometry "similar".

Answer 26

yes, okay gotcha. thats what was really confusing me what the size

Answer 27

Similar means that every angle in UVWX will be equal to the corresponding angle in PQRS, and every length (side) in UVWX will be scaled by the same factor, which is 3.

Answer 28

okay

Answer 29

So now the tricky part. In your diagram the point D corresponds to S (-8,3). How far down and to the left from A is it in the figure?

Answer 30

10

Answer 31

It is -3 in the x-direction and -4 in the y-direction.

Answer 32

oh okayyy

Answer 33

So, multiply by 3

Answer 34

each number?

Answer 35

Yes

Answer 36

I'll do it, it's -9 in the x-direction and -12 in the y-direction. OK?

Answer 37

yeah thats what i go too

Answer 38

So what you need to do is start from point U or E (-2,-1) and go -9 in the x-direction and -12 in the y-direction.

Answer 39

okay one sec

Answer 40

but it makes a straight line

Answer 41

Of course.

Answer 42

ABCD is a trapezoid. Do you know what a trapezoid is?

Answer 43

rather PQRS

Answer 44

yes

Answer 45

Well, OK. This is going to be the slanted left side of our new, bigger trapezoid UVWX.

Answer 46

k

Answer 47

Sure you're with me?

Answer 48

yes

Answer 49

So the coordinates of the new point are (-11, -13).

Answer 50

alrighty

Answer 51

Now the last one.

Answer 52

Start from point Q (-2,7) go to point R (2,3) that is 4 units to the right on the x-axis and 4 units down on the y-axis. Can you do the multiplication by 3?

Answer 53

wait how did you get (-11,-13) ?

Answer 54

That was starting from point U or E (-2,-1) and going -9 in the x-direction and -12 in the y-direction.

Answer 55

oh right

Answer 56

If you prefer, 9 in the minus-x direction and 12 in the minus-y direction.

Answer 57

alright jerk, Im not that fluttering dumb. Peace ✌

Answer 58

fluttering*

Answer 59

bye

Answer 60

effing*
