Question

can a quadrilateral ABC be a parallelogram if @ {d+{b=180°?(ii)AB=DC= 8cm, AD= 4 cm and BC = 4.4 cm?(iii) {A=70° and {c=65°?
​

Answer 1

Answer:

Let's look into a quadrilateral ABCD and check if it is a parallelogram using the following conditions: (i) For, ∠D + ∠B = 180°, ABCD may or may not be a parallelogram (ii) For, AB = DC = 8 cm, AD = 4 cm and BC = 4.4 cm, ABCD cannot be a parallelogram (iii) For, ∠A = 70° and ∠C = 65°, ABCD cannot be a parallelogram.

Answer 2

Answer:

No, this can't form a parallelogram.

Step-by-step explanation:

In a Parallelogram, Opposite sides MUST BE equal and parallel, which are not as AD ≠ BC

Opposite angles also MUST BE equal, which are not as ∠A≠∠C

So, yeah, it can't be a prallelogram.
