Question

if (-2,-1)(1,0)(4,3) ar three successive vertices of a parallelogram find the fourth vertex​

Answer 1

Answer:

(1,2)

Step-by-step explanation:

C(4, 3) and D(x, y) be the vertices of a parallelogram ABCD taken in order. Since, the diagonals of a parallelogram bisect each other. Therefore coordinates of the mid-point of AC = Coordinates of the mid-point of BD. Therefore (1,2) is the fourth vertex.
