Which statement is true?

All parallelograms are quadrilaterals.

All parallelograms are rectangles.

All parallelograms are squares.

All parallelograms are rhombuses.

All parallelograms are quadrilaterals

Step-by-step explanation:

Not all can be rectangles because the angles will sometimes be > 90° and/or < 90°.

Same reason to why it cannot always be a square.

All rhombuses are parallelogram. This is because rhombuses have two pairs of parallel sides. But only some parallelograms are rhombuses, because only some parallelograms have four equal sides.

All parallelograms are quadrilaterals
