Answer 2

Given: A quadrilateral KLMN having

∠L=80°

and ∠M=100°

Proof: For line segment NM and KL, with MO transversal.

∠M+∠L=180°

Thus,

Sum of interior angles on the same side of transversal is 180°

Which is only possible if NM and KL are parallel lines.

∴ NM║KL

Since, KLMN is a quadrilateral with KL║NM

∴KLNM is a trapezium
