Final answer:
A rhombus is a type of parallelogram that has all sides congruent and opposite angles congruent. A parallelogram is a quadrilateral with two pairs of parallel lines. A polygon is any closed figure made up of line segments.
Step-by-step explanation:
A rhombus is a quadrilateral with all sides congruent and opposite angles congruent. A parallelogram is a quadrilateral with two pairs of parallel lines. A polygon is a closed figure made up of line segments.
For example, a rhombus can be a parallelogram but not all parallelograms are rhombuses. Similarly, a polygon can be any closed figure made up of line segments, whether it is a triangle, quadrilateral, or a more complex shape.
So, to summarize:
A rhombus is a type of parallelogram that has all sides congruent and opposite angles congruent.
A parallelogram is a quadrilateral with two pairs of parallel lines.
A polygon is any closed figure made up of line segments.
