What is the difference between a Polygon and a Parallelogram?
A polygon is any closed shape with straight, non-crossed lines - but a parallelogram is a special kind of polygon that has two sets (or pairs) of parallel sides. (NOT two parallel sides, and NOT four parallel sides)

Are all rhombi squares? Explain.
No, a rhombus is a shape with 4 equal sides, but it doesn't ALWAYS have 4 right angles. A rhombus can be a square OR a "diamond". A square has 4 equal sides AND 4 right angles.
