what has 4 congruent sides and opposite sides are parallel

Question

hat has 4 congruent sides and opposite sides are parallel

Answer 1

A rhombus has all sides congruent, and because it's a parallelogram, it's opposite sides are most certainly parallel.  A square IS a rhombus, so a square is correct also. But a square isn't the most general answer. Hope this helps. 

Answer 2

A square has all 4 sides congruent/equal and the opposite sides are parallel to each other, which means, if we extend the opposite sides they will touch each other or intersect.
