a) (0,1) b (0,-1) c (-1,0) d (1,0)​

Answer 1

Answer:

The fourth vertex D of a parallelogram ABCD whose three vertices are A(-2,3), B(6,7) and C(8,3) is. Let the fourth vertex of parallelogram , D ≡(x4,y4)and L,M be the middle points of AC and BD , respectively. Hence , the fourth vertex of parallelogram is D ≡(x4,y4)≡(0,1).

Answer 2

Since, ABCD is a parallelogram, therefore diagonals AC and BD will bisect each other. Hence, L and M are the same points. Hence, the fourth vertex of parallelogram is D s (x , y ) s (0,-1).
