Question

EXERCISE 6.5
1. Sides of triangles are given below. Determine which of them are right triangles
In case of a right triangle, write the length of its hypotenuse.
(1) 7 cm, 24 cm, 25 cm
(ii) 3 cm, 8 cm, 6 cm
(iii) 50 cm, 80 cm, 100 cm
(iv) 13 cm, 12 cm, 5 cm
D​

Answer 1

Answer:

iv) 13cm, 12cm, 5cm

Step-by-step explanation:

longer side is hypotenuse so 13 cm is length of hypotenuse

Answer 2

Answer:

1 and 4

Step-by-step explanation:

In case of right triangles, look for Pythagorian triplet.

      $base^{2} + altitude^{2} = hypotenuse^{2}$

• $7^{2} + 24^{2} = 25^{2}$    
• $12^{2} + 5^{2} = 13^{2}$
