Question

Three vertices of a parallelogram taken in order are (0,3) (0,6) and (2,9). Find the fourth vertex​

Answer 1

Step-by-step explanation:

Assume fourth vertex (x,y)

Using distance formula find sides of parallelogram

and equate the opposite side as they are equal.

you will get coordinate of fourth vertex.

Answer 2

use formula x4=X1+x3-x2

y4=y1+y3-y2

(x4,y4)=(0+2-0,3+9-6)

=(2,6)
