Question

State the reason why MN = LK.

Answer 1

Because of you were to fold the shape in half it is just a REFLECTION of the same thing so therefore one side is going to equal the other since they are the exact same shape.

Answer 2

Answer:

Given:  

KLMN is a parallelogram  

Area of parallelogram: A parallelogram is a simple quadrilateral with two pairs of parallel sides.

In parallelogram KLMN as shown below in figure.

By definition:

$KL || MN$ and $LM || KN$

Since, the opposite sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Therefore;

$KL = MN$
