Answer:
i) Given, a=7,cm,b=24cm and c=25cm
c2=a2+b2 [ By using Pythagoras theorem ]
c2=72+242
c2=49+576
c2=625
∴ c=25cm
Hence, the given triangle is right angled triangle.
(ii) given, a=9cm,b=16cm and c=18
c2=a2+b2 [ By using Pythagoras theorem ]
c2=92+162
c2=81+256
c2=337
∴ c=18.35cm
Hence, the given triangle is not right angled triangle.
(iii) given, a=1.6,cm,b=3.8cm and c=4cm
c2=a2+b2 [ By using Pythagoras theorem ]
c2=(1.6)2+(3.8)2
c
