Concept:A square is a special quadrilateral that fits the definitions of a rectangle, rhombus, and parallelogram.
Explanation:A rectangle has four right angles. A square also has four right angles, so it is a rectangle.
A rhombus has all four sides equal. A square has all sides equal, so it is a rhombus.
A parallelogram has both pairs of opposite sides parallel. A square’s opposite sides are parallel, so it is a parallelogram.
Since a square satisfies all three conditions, it can be called a rectangle, a rhombus, and a parallelogram.
Answer:D. All of these
