the diagonals bisect each other.
So the midpoint M is halfway from W to Y and halfway from X to Z
M = (W+Y)/2
Y = 2M-W = 2(6,-4)-(4,-2) = (12,-8)-(4,-2) = (8,-6)
now do Z in like wise.
or, you could just plot the three points and extend the diagonals an equal distance to get to the other vertices.
The two vertices of parallelogram WXYZ
are W(4, -2) and X(9, 0), and the
intersection of the diagonals is A(6, -4).
Find the coordinates of the other two
vertices.
