What are all the names for a perallelogram?

Answer 1

A parallelogram is commonly referred to by several names based on its specific properties, including rectangle (if all angles are right angles), rhombus (if all sides are equal), and square (if it meets both criteria of a rectangle and rhombus). Other less common terms include trapezium in British English, which refers to a quadrilateral with at least one pair of parallel sides, though this does not describe all parallelograms. Overall, the most accurate and general term remains "parallelogram."
