If a transversal line is intersecting two given lines such that the sum of the measures of the angles on the same side of transversal is 180°, then the given two lines will be parallel to each other.
Here, ∠NML + ∠MLK = 180°
Hence,NM||LK
As quadrilateral KLMN has a pair of parallel lines, therefore, it is a trapezium.
