Question

Three consecutive vertices of //gm are (5, 6), ( 2, 8) and ( 0, 6). Find the fourth vertex.​

Answer 1

Answer:

An atmosphere is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.An atmosphere is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body.

Answer 2

Diagonals of a parallelogram bisect each other,
let the point of intersection of diagonals be M(m,n)

m=
2
−2+4
​
=1 and n=
2
−1+3
​
=1

∴m=1 and n=1

Let the Fourth vertex be D(x,y)

⇒ m=
2
1+x
​
=1 and n=
2
0+y
​
=1

x+1=2 and y=2

Thus x=1 & y=2

The fourth vertex of the parallelogram is D≡(1,2)
