Class 8 chapter number 3 exercise 3.3 question number 10
Q10 :
Explain how this figure is a trapezium. Which of its two sides are parallel
Answer :
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 180ยบ, 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.
