Question

.(6, 1), (8.2) and (9.4) are three vertices of a parallelogram taken in order. Find the 4th vertex​

Answer 1

Answer:

Solution :

We know, diagonals of a parallelogram bisects each other.

It means,

Midpoint of AC = Midpoint of BD

As, we have to find value of p, we will take only x coordinates of AC and BD.

6+92=8+p2

⇒15=8+p⇒p=7
