21. Four types of quadrilaterals are:
- Square: A square is a quadrilateral with all sides of equal length and all angles of equal measure (90 degrees). It is a regular quadrilateral.
- Rectangle: A rectangle is a quadrilateral with opposite sides of equal length and all angles of equal measure (90 degrees). It is an equilateral quadrilateral.
- Rhombus: A rhombus is a quadrilateral with all sides of equal length. Its opposite angles are equal, but the angles are not necessarily right angles. It is an irregular quadrilateral.
- Trapezoid: A trapezoid is a quadrilateral with exactly one pair of parallel sides. The other two sides are not parallel. It is an irregular quadrilateral.
22. Yes, the figure on the right is congruent to the sample figure. Two rectangles are considered congruent when all of their corresponding sides and angles are equal in measure. In this case, both rectangles have sides of 3 cm, 7 cm, 3 cm, and 7 cm, which are exactly the same. Therefore, the two rectangles are congruent.
