THE TWO OPP. VERTICES OF A SQUARE ARE (-1,2) AND (3,2). FIND DA CO-ORDINATES OF THE OTHER 2 VERTICES

BD will also have (1, 2) as the mid point. If the vertices of point B is (1,0), then
(x1+1)/2 = 1
x1 = 1
and (y1+0)/2 = 2 or y1 =4
or if B has vertices (1, 4), then y1 =0.
Thus, either B(1,0) and D(1,4) or B(1,4) and D(1,0).
