Question

Three vertices of a parallelogram are (1,0) 2 0 5 1

Answer 1

Answer:

this you solve by _/x1(y3-y2)x2(y2-y1)x3(y2-y1)

Answer 2

Answer:

The point is D(4,1)

Step-by-step explanation:

I am guessing you want us to find fourth vertex.

Const. - Join the diagonals of the parallelogram.

We know that the diagonals of a parallelogram bisect each other.

Assume the centere point as O(a,b) and fourth vertex as (x,y)

On line segment AOC,

O((1+5)/2, (0+1)/2) = O(3, 1/2)    -----[1]

On line segment  BOD

O((2+x)/2, (0+y)/2)                    ------[2]

From [1] & [2]

2+x = 6 ⇒ x = 4,   1/2 = y/2 ⇒ y = 1
