Step-by-step explanation:

sides opposite to equal angles are equal in length :

angle45 = angle 45

r = s

by Pythagoras theorem :

r² + s² = (9√2 )²

s²+s²= 9 × 9 × 2

2s²= 9× 9×2

s²= 9 × 9

s= √9× 9

s = 9

r= s = 9 units .

plz mark my answer as brainlist plzzzz hope this will be helpful to you.
