Question

Which of the following Pythagorean triplets?
(i) (2, 2, 2) (ü) (3,4,5) (ii) (9, 12, 15)
(iv) (6,5,7)​

Answer 1

Answer:

Step-by-step explanation:

a pythagorean triplet is the one which follows the rule that a^2+b^2=c^2

in ii) we can see that as 3^2+4^2=5^2 so ii ) is correct

in iii) as 9^2+12^2=15^2 so iii) is also correct

Answer 2

Answer:

(ii) (3,4,5) and (iii) (9,12,15) are Pythagorean Triplet.

Explanation:

Here, the 5 is greater than 3 and 4.

So, 5 is a hypotenuse

By the Pythagoras Theorem

(hy)2= (b)2+(h)2

5^2 = 4^2+3^2

25= 16+9

25= 25 -----(Pythagorean Triplet)
