Yes. ABC is a right angled triangle bcoz
ad =12, bd = 9 therefore ab = 15cm.(By Pythagoras triplet.)
ad = 12, DC = 16 Therefore Ac = 20cm(By Pythagoras triplet.)
Now, AB = 15cm, AC = 20 cm, then BC = 25 cm.[( 15,20,25) is a Pythagoras triplet]
ad =12, bd = 9 therefore ab = 15cm.(By Pythagoras triplet.)
ad = 12, DC = 16 Therefore Ac = 20cm(By Pythagoras triplet.)
