State the reason why mn = lk .

given:
klmn is a parallelogram.

MN = LK because of the definition of a 'parallelogram'.

Step-by-step explanation:

We are given a parallelogram KLMN.

We know that a 'parallelogram' is a quadrilateral which have two opposite sides parallel and equal in length.

Therefore, from parallelogram KLMN, we get,

MN║LK and ML║NK

MN = LK and ML = LK.

Hence, we that MN = LK because of the definition of a 'parallelogram'.

Proof is below.

Step-by-step explanation:

Given: KLMN is a parallelogram.

To Prove: MN = LK.

Statement: MN = LK.

Reason: MN = LK by definition of a parallelogram; a quadrilateral whose sides are parallel and thus, equal in measure.  Therefore, your answer would be 'Definition of parallelogram', or if your work requests that you explain further, it is the latter statement.  The sides are not only parallel, but equal.

Hope this helps.
