A square is a rectangle. Mathematically yes always, a rectangle is any quadrilateral with four internal right angles. A rectangle is a parallelogram. Mathematically yes always: a paralellagram is any quadrilateral with two pairs of parallel sides, such as a rectangle. A parallelogram is a square. If the parallelogram has four equal sides AND it has four internal right angles, THEN it is a square. So "occasionally". A rhombus is a square. Only if it has four internal right angles. So "occasionally". A rhombus is a rectangle. If it has four internal right angles, then yes. So "occasionally". A square is a trapeziod. Can't answer this because trapeziod has several incompatible definitions.
