The diagonals of quadrilateral EFGH intersect at D(3,3). EFGCH has vertices at E(4,7) and F(-3,5). What must be the coordinates of G and H to ensure that EFGH is a parallelogram.

Step-by-step explanation:

Given

--- Diagonal

Required

Determine the coordinates of G and H

Since EFGH is a parallelogram, then:

D is the midpoint of EG and EF

For EG, we have:

Where x, y are the coordinates of G.

Multiply both sides by 2

By comparison:

==>

==>

So:

For FH, we have:

Where x, y are the coordinates of H.

Multiply both sides by 2

By comparison:

==>

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.
