**Reiny**, Tuesday, January 17, 2012 at 1:50pmSimplest way, just count on the grid ...

you have 3 points, and you know that opposite sides must be parallel and equal

A quick calculation shows that each of the given sides is √65 , so far so good.

For the line from (1,0) to (0,-8) we went one to the left, then 8 down

so from (8,-4) go 1 left, then 8 down to get

(7, -11)

(check by taking the lengths of the new lines, I did,

they were both √65)
