Question

6. In a quadrilateral ABCD, AB = 6 cm,
CD = 8 cm and sum of angles A and D is
180°. This is --​

Answer 1

Answer:

It is a trapezium...

as the sum of co interior angles is 180 in parallel lines

Answer 2

ABCD is a trapezium

Step-by-step explanation:

This is a Trapezium

because

if sum of angles A and D is  180° it means that the line AB and CD are parallel

(sum of the co interior angles )

it can't be a parallelogram because , in a parallelogram opposite sides are equal and parallel but here the opposite sides are different .

and in trapezium the opposite lines are parallel as well as the measure of the both lines are different

hence ,

ABCD is a trapezium
