Sometimes they are.
Some parallelograms are squares - the ones which are equiangular (have equal angles) and are equilateral (have equal side lengths). All squares are parallelograms, but only some parallelograms are squares.

Yes
Perfect squares will never be irrational numbers. A perfect square is the result of multiplying an integer by itself, which always yields a rational number. Since the square root of a perfect square is an integer, perfect squares are always rational. Thus, they cannot be irrational.
A rectangle is sometimes a square. Specifically, a square is a special type of rectangle where all four sides are of equal length. Therefore, while all squares are rectangles, not all rectangles are squares.
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.

-- A parallelogram is always a quadrilateral. -- A quadrilateral is sometimes a parallelogram.

It is sometimes true that two parallelograms are similar. The could be congruent, or dissimilar in that one is not an enlargement of the other.
Yes
Sometimes * * * * * Never. A parallelogram has two pairs of equal angles opposite one another. A trapezoid does not.

No. Parallelograms are never trapezoids. Trapezoids are never parallelograms.

Never, honey. Just because a parallelogram has those fancy opposite sides that are parallel, doesn't mean it automatically becomes a rectangle. Rectangles have those nice right angles, while parallelograms can be all slanted and sassy. So, keep those shapes in check, darling.
A quadrilateral always has four sides.A square always has four sides→ a square is always a quadrilateral.A quadrilateral's only distinguishing feature is a shape with four sides.A square has four sides, but also those four sides must all be the same length and all the angles are the same, at 90o.So squares are always quadrilaterals, but quadrilaterals are only sometimes squares.
