Question

Which of the following statements does not prove that ABCD is a parallelogram.

Given: A(-4, 7), B(3,0), C(2,-5) and D(-5, 2).

Answer 1

answer A

Explanation:

A=(-4,7)

C=(2,-5)

midpoint = U=((-4+2)/2, (7+(-5))/2)=(-1,1))

B=(3,0)

D=(-5,2)

midpoint = V=((3+(-5))/2,(0+2)/2)=( -1,1)

Diagonals have the same middle, the quadrilater is a parallogram.
