The correct statement proves that parallelogram KLMN is a rhombus.
The slope of KM is 1 and the slope of NL is –1.
<h3>What is the rhombus?</h3>
A rhombus is a parallelogram whose all sides are equal. Its diagonals perpendicularly bisect each other.
If one line is perpendicular to the other lines then the product of its slope should be -1.
The slope of the KM is;

The slope of the KM is 1.
And the slope of NL is;

The slope of NL is -1.
Hence, The slope of KM is 1 and the slope of NL is –1.
