Question

Decide whether the quadrilateral is a parallelogram. Explain your answer.

Answer 1

Answer: all of them are parallelograms

Explanation:
In this case, every shape is exactly the same and every side is parallel to each other, so they are all parallelograms. In other cases, like a trapezoid, 2 sides are not parallel, so the trapezoid is not parallelogram, only a quadrilateral.
