Is the triangle with sides 25 cm,

False

Let a = 25 cm, b = 5 cm and c =24 cm

Now,                                             b2 + c2 = (5)2 + (24)2

                                                                     = 25+ 576 = 601 ≠ (25)2

Hence, given sides do not make a right triangle because it does not satisfy the property of Pythagoras theorem.
