Question

Hello! I need someone to explain to me how to do this. Thanks!!!

Answer 1

Let the fourth vertex be (x, y).
Diagonals AC and BD bisect each other
=> their mid-points are the same

Start this way

Answer 2

I HAVE NO CLUE WHAT YOU JUST SAID @.@

Answer 3

So now we must figure out that point correct? Look at the difference from each x point around the square and each y point around the square

Answer 4

since our missing point is on the bottom left side, the x coordinate for the bottom left is -4 because that is what the top right x coordinate is and they have the same x just like the two corners on the right have the same x and it goes the same for y, the bottom right point has a y value of -4 so that means the missing point has a y value of -4

Answer 5

I don't get it

Answer 6

Or you didn't read it ??

Answer 7

look at the left side of the square! it is -4 units away from the (0,0) so now that means both corners are -4 units away from 0,0 because they connect straight down. Correct?

Answer 8

@jigglypuff314 if she cannot understand my logical reasoning that is simple to find the answer, she is deffinetly not going to understand the mathematical procedure required to find the answer

Answer 9

(-4,-4) is the answer. In a square all the sides are equal. So find the distance between the sides using the formula \[\sqrt{(y2-y1)^2+(x2-x1)^2}\]

Answer 10

look at the picture baseballer drew for you, see that each point is two units away from each other.
from (-4, -2) go down two units, that will give you the point you are looking for

Answer 11

@Harsha19111999 , that was just what she was looking for BUT
