Question

Three vertices of a rectangle are the points (3,4), (-1,2) and (2,-4).The co-ordinates of the fourth vertex are

Answer 1

Let A(3,4). B(-1,2). C(2,-4)
Take out mid point of A and C
x=3+2/2. y=4-4/2
x=5/2. y=0/2
x=2.5. y=0
M(2.5,0)

Now from mid point and B we will take out fourth vertex.
x=2.5-1/2. y=0+2/2
x=2. y=1
(2,1)

Answer 2
