Question

Examine whether the triangles having given sides are right anded trangle or not
(a) 5 cm, 12 cm and 13 cm
(b) 4 cm, 5 cm and 6 cm
(c) 7 cm. 24 cm and 25 cm​

Answer 1

Answer:

a) 13^2 = 12^2 + 5^2

By pythagoras theorem

169 = 144 + 25

169 = 169

Therefore it is a right angled triangle.

b) 6^2 = 5^2 + 4^2

36 = 25 + 16

36 = 41

Therefore it is not a right angled triangle

c) 25^2 = 24^2 + 7^2

625 = 576 + 49

625 = 625

Therefore it is a right angled triangle.
