A quadrilateral is a shape with 4 sides, regardless of their lengths, angles, or symmetry.
Therefore, a square is always a quadrilateral.
Answer:
13
Step-by-step explanation:
there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.
