    Answer:

    (i) Given, a=7,cm,b=24cm and c=25cm

    c

    2

    =a

    2

    +b

    2

    [ By using Pythagoras theorem ]

    c

    2

    =7

    2

    +24

    2

    c

    2

    =49+576

    c

    2

    =625

    ∴ c=25cm

    Hence, the given triangle is right angled triangle.

    (ii) given, a=9cm,b=16cm and c=18

    c

    2

    =a

    2

    +b

    2

    [ By using Pythagoras theorem ]

    c

    2

    =9

    2

    +16

    2

    c

    2

    =81+256

    c

    2

    =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

    c

    2

    =a

    2

    +b

    2

    [ By using Pythagoras theorem ]

    c

    2

    =(1.6)

    2

    +(3.8)

    2

    c

    2

    =2.56+14.44

    c

    2

    =17

    ∴ c=4.12cm

    Hence, the given triangle is not right angled triangle.

    (iv) given, a=8,cm,b=10cm and c=6cm

    b

    2

    =a

    2

    +c

    2

    [ By using Pythagoras theorem ]

    b

    2

    =(8)

    2

    +(6)

    2

    b

    2

    =64+36

    b

    2

    =100

    ∴ b=10cm

    Hence, the given triangle is right angled triangle.
