State the reason why ml ii nk.

given:
klmn is a parallelogram.

Since KLMN is parallelogram, the opposite set of pairs will always be parallel. This is a property of a parallelogram.

Therefore,

ML || NK
and
LK || MN

The reason behind this is the slope or inclination of opposite sides is the same. i.e. both sides rise or fall at the same rate. The slopes are same because the angles made by the opposite sides are equal in magnitude. As a result the opposite sides are always parallel.
