2. Invalid. Additional information needed: The diagonals are perpendicular or one angle is a right angle.

3. Invalid. Additional information needed: The diagonals bisect each other or opposite sides are parallel.

4. Invalid. Additional information needed: The diagonals bisect each other or opposite sides are equal.

5. Valid. Since AB ∥ DC and AD ∥ BC, ABCD is a parallelogram. Given AC = BD, a parallelogram with congruent diagonals is a rectangle.

6. EG = 5, FH = 5, slope of EG = 1, slope of FH = -1 → Rectangle, Rhombus, Square

7. PR = 2√2, QS = 2√2, slope of PR = -1, slope of QS = 1 → Rectangle, Rhombus, Square
