The document defines and compares different types of quadrilaterals. It states that a parallelogram has two pairs of parallel sides, a rectangle has four right angles and opposite sides that are parallel and the same length, and a square has four right angles and all sides the same length. A rhombus has two pairs of parallel sides and all sides the same length, while a trapezoid only has one pair of parallel lines. All squares are rectangles and parallelograms, all rectangles are quadrilaterals, and parallelograms are not necessarily rectangles.
8. Looking at the chart, answer the following questions: Are all rectangles quadrilaterals? Are all squares rectangles? Are all rectangles squares? Are all parallelograms rectangles? Are all squares parallelograms?
