Question

What is the most precise name for quadrilateral ABCD with vertices A(-4,-1), B(-2,-5), C(4,-2) and D(2,2)?
Parallelogram
rhombus
quadrilateral

Answer 1

So, I used the midpoint formula. M = x1 + x2/2, y1 + y2/2
AB M = (-1 + -2/2, -1 + -5/2) = (-1.5,-3)
BC M = (-2 + 4/2, -5 + -2/2) = (1,-3.5)
CD M = (4+ 2/2, -5 + -2/2) = (3,0)
DA M = (2 + -4/2, 2 + -1/2) = (-1,0.5)

Answer 2

I forgot the fourth option, rectangle

Answer 3

is the forth option \(\huge kite\)

Answer 4

no

Answer 5

Answer 6

there is one more step to the problem to find out but I can't figure it out

Answer 10

How do you tag people on here?

Answer 11

@School_is_hard

Answer 12

oh ok thank you

Answer 13

well at the previous it is written in the question to find the midpoint , but in your posted question ,it is not so, so no need to find midpoint here

Answer 14

oh ok, so how do I find out which answer it is?

Answer 15

see each link and the figures in there

Answer 16

I know what they look like. But I don't think they are wanting me to go by looks. because in the book a parallelogram would be a slope of -1, A triangle classifying isosceles, scalene, equilateral, and thing like that

Answer 17

quadrilateral can be any figure with four sides

Answer 18

so what u think what is the answer

Answer 19

do u have to right a paragraph or something as long for answer

Answer 20

ether a quadrilateral or a rombus

Answer 21

i meant rhombus

Answer 22

no its multiple choice

Answer 23

\(\huge no\)

Answer 24

and I have two like this one

Answer 25

do u think in the figure the opposite sides are equal

Answer 26

no

Answer 27

it is the red figure right ?

Answer 28

no the green

Answer 29

look at the page I sent page 402 explains it

Answer 30

in the question the co-ordinates u gave only matches with the red figure

Answer 31

yes but the green is what I got from finding the midpoints

Answer 32

And on page 402 you have to find the midpoint then distance of the green to classify the figure

Answer 33

but i said earlier that u didnot need to find the midpoint here like the previous question as it is not written in the question to find the midpoint
