The points A(1, -2, 4), B(3, 5, 7), C(4, 6, 8) are three of four vertices of parallelogram ABCD. Determine the coordinates of vertex D

Could someone please tell me to go about solving this question. Thanks a lot.

  • Math -

    Calculate vector BA and add it to point C to get point D, similar to sliding the line BA until it fits on C.
    Vector BA
    = coordinates of A - coordinates of B.
    =(1,-2,4) - (3,5,7)

    You can take it from here.

    Do check your calculations by comparing the mid-points of AC and BD. They should be identical since the diagonals of a parallelogram bisect each other.
