Consider the figure shown. What type of quadrilateral can it be?
Parallelogram
In the given figure the pair of opposite sides are parallel and equal. So, the given figure is a parallelogram.
Among the options, the quadrilateral ABCD can be either 'Rhombus' or 'Parallelogram'. [∵ Rhombus is also a parallelogram]
But adjcent sides of ABCD are not equal (i.e., AD and CD are not equal).
So, ABCD cannot be a rhombus. Hence, ABCD is a paralleogram.
