Question

Three consecutive vertices of a parallelogram are (-2 1)

Answer 1

hlo mate ✌️

A (-2,-1) = (x1 , y1)

B (1,0) = (x2,y2)

C(4,3) = (x3,y3)

We have to find D(x4,y4)

To find x4,

(x1 + x3) = ( x2+x4)

-2 + 4 = 1 + x4

2 -1 = x4

x4 = 1

To find y4,

y1 + y3 = y2 + y4

-1 + 3 = 0 + y4

x4 = 2

So the 4th vertex = (1,2)

Hope it helps.
