These two segments (DG and EH) should come out to be of equal distance.
The coordinates of D are (-2h, 0) and G are (h,k).
Using the distance formula I got the distance of DG to be the square root of 3h squared + k squared.
Using the distance formula I got the distance of EH to be -3h squared + k squared.
I know the two distances should be equal. I don't know why the second segment is coming out with that negative 3. I must have made a mistake somewhere... please help.

You did not state the coordinates of E and H.

how do i fid the surface are for this shape??? HELP!

• geometry -

oops.
E (2h, 0)
A (0, 2k)

• geometry -

oops again.
E (2h, 0)
H (-h, k)

• geometry -

EH = √(2h-(-h))^2 + (0-k)^2)
= √(9h^2 + k^2)
which is the same as your other length

how could it be 9h squared? If you squared the 3? shouldn't that.. square be gone? I don't understand...

Hey thanks, stupid negative..... Ok now I'm trying to figure out the distance formula. the coordinates are (-1,3) and (2,5) So I take (5-3)^2 + (2-1)^2 and get 2^2 + 1^2. so 4 + 1 is 5. so the square root of 5 is the answer?
