Q2 of 45 Page 43

Solve the following examples.

Do sides 7 cm , 24 cm, 25 cm form a right angled triangle ? Give reason.


Yes,


Because


72 + 242 = 252 [i.e. 49 + 576 = 625]


As, sides satisfy the Pythagoras theorem, i.e.


(Hypotenuse)2 = (base)2 + (Perpendicular)2


They do form a right-angled triangle.
