Question

Diagonal of a quadrilateral ABCD bisect each other if a=35 determine b

Answer 1

Solution :-

Diagonals of a quadrilateral bisect each other then, the given quadrilateral is a parallelogram.

So, ABCD is a parallelogram.

Now, ∠ ABC and ∠ DAB at=re consecutive interior angles as AD II BC and AB is a transversal.

As we know that the sum of consecutive interior angles is always 180°.

∴ ∠ ABC + ∠ DAB = 180°

⇒ ∠ ABC = 180° - ∠ DAB

⇒ ∠ ABC = 180° - 35°

⇒ ∠ ABC = 145°
