Answer 1

Answer:

Quadrilateral ABCD is a trapezium and not a parallelogram.

Step-by-step explanation:

It is not a parallelogram because in a parallelogram, the opposite angles are equal but here, ∠A ≠ ∠C and ∠B ≠ ∠D.

So, it is not a parallelogram.

It is a trapezium because in a trapezium, the sum of two adjacent angles is 180°.

Here,

∠A + ∠D = 80 + 100 = 180° and

∠B + ∠C = 40 + 140 = 180°.

So, it is a trapezium.
