Answer 1

HERE IS THE ANSWER FOR YOUR QUESTION;

◆ The answer is No.

◆◆ Justification ◆◆

We know that the opposite side of a parallelogram are equal in length. Here one of the pair of sides are equal but the other are not.


According to this question, Geometrically they are equal as Angle B = Angle D = 80° so the opposite sides are equal ie., BC =AD [By theorem] but here they are not equal due to different lengths of the sides given of AD & BC.
