Answer:
KITE
Step-by-step explanation:
We are given that,
Quadrilateral ' adqu ' is congruent to quadrilateral ' teki '.
i.e. adqu ≅ teki
Now, when two figures are congruent the position of the letters are very important.
Using the positioning of the letters, we will find the quadrilateral congruent to ' quad '.
So, we see that the correspondence of letters is given by q → k, u → i, a → t and d → e.
Therefore, quad ≅ kite.
Hence, Quadrilateral ' quad ' is congruent to quadrilateral ' kite '.
