Question

ASAP HELP ME PLEASE
The endpoints of one diagonal of a rhombus are (0, -8) and (8, -4). If the coordinates of the 3rd vertex are (1, 0), what are the coordinates of the 4th vertex?


(7, -12)
(7, -8)
(-8, -4)
(-4, -12)

Answer 1

See rhombus is a parallelogram hence the diagonals of the rhombus here must bisect each other

Answer 2

so first find the midpoint of (0, -8) and (8, -4)
the mid point is (0+8)/2 ,(-8-4)/2 (4,-6)
Now (4,-6) is also the midpoint of (1,0) and the 4th vertex

Answer 3

so 4th vertex is (7, -12)
