If ABCD is congrunent to, pqrs, then AD is congrent to?

AD is congruent to RS

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

If

ABCD≅PQRS

then

Corresponding angles

∠A≅∠P

∠B≅∠Q

∠C≅∠R

∠D≅∠S

Corresponding sides

AB≅PQ

BC≅QR

CD≅RS

AD≅PS
