1. Special Quadrilaterals Practice
Honors Geometry

2. Give the most descriptive name
A quadrilateral with perpendicular diagonals must be a: _______________
Give the most descriptive name

3. Quadrilateral
(Diagonals don’t have to bisect each other or be perpendicular!)
Answer

4. Give the most descriptive name
A parallelogram with perpendicular diagonals must be a: ______________
Give the most descriptive name

5. Rhombus
(Parallelogram diagonals must bisect each other. Diagonals don’t have to be congruent, but are perpendicular. Forms 4 congruent triangles (SAS), so 4 congruent sides.)
Answer

6. Give the most descriptive name
A quadrilateral in which both diagonals bisect the opposite angles must be a _________________.
Give the most descriptive name

7. Rhombus
Answer

8. Give the most descriptive name
A kite with congruent diagonals must be a: ____________________
Give the most descriptive name

9. Kite – could be square, but given doesn’t say diagonals have to bisect each other! Could be:
Answer

10. Give the most descriptive name
A parallelogram with diagonals bisecting opposite angles must be a: ___________
Give the most descriptive name

11. Rhombus
(Opp. angles of parallelogram are congruent, so halves of angles are congruent, forming isos. triangles with congruent sides. Opp. sides of parallelograms are congruent, so all 4 sides must be congruent.
Answer

12. Give the most descriptive name
A rhombus with congruent diagonals must be a: ___________________
Give the most descriptive name

13. Square
(A parallelogram with congruent diagonals must be a rectangle, which has 4 rt. angles. A rhombus has 4 congruent sides. A shape with 4 congruent sides and angles is a square!)
Answer

14. Give the most descriptive name:

15. Parallelogram
(Diagonals bisect each other)
Answer

16. Give the most descriptive name

17. Quadrilateral
(Diagonals do not have to be same length or bisect each other. Could look like diagram below: )
Answer

18. Give the most descriptive name

19. Quadrilateral (Could be either trap or parallelogram, so not enough info to classify)
Answer

20. Give the most descriptive name

21. Kite
(One diagonal is perp. bis. of the other, so the Equidistance Theorem applies)
Answer

22. Give the most descriptive name

23. Rhombus
(Bisecting diagonals means it must at least be a parallelogram, but 4 congruent sides makes it a rhombus.)
Answer

24. Give the most descriptive name

25. Quadrilateral – Could be isos
Quadrilateral – Could be isos. trapezoid, but could also be parallelogram since it is not stated that sides of length 8 AREN’T parallel… categories don’t overlap, so it is only known that the shape has 4 sides
