• 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

Answer:

The fourth vertex D of a parallelogram ABCD whose three vertices are A(–2, 3), B(6, 7) and C(8, 3) is (0, –1).

Since, ABCD is a parallelogram, therefore diagonals AC and BD will bisect each other.

Hence ,option d)
