Solution

(i) Given that the sides of the triangle are 7 cm, 24 cm, and 25 cm.
Squaring the lengths of these sides, we will get 49, 576, and 625.
49 + 576 = 625
(7)2+(24)2=(25)2
The sides of the given triangle are satisfying Pythagoras theorem.
Hence, it is a right-angled triangle.
Length of Hypotenuse = Length of the longest side = 25 cm
