(1) (2,2, 2)
(ii) (3,4,5)
(iii) (9, 12, 15)​

Answer 1

Answer:

(i)(9,8,10)

Since these numbers do not follow Pythagoras theorem, we can say that this is not a Pythagoras triplet

(ii)(4,3,5)

Since 5

2

=4

2

+3

2

So, this is a Pythagorean triplet.

(iii)(6,8,10)

Since 10

2

=8

2

+6

2

so, this is a Pythagorean triplet

Answer 2

Answer:

(ii)(3,4,5)

Step by Step explanation

n²-1,2n,n²+1 are members of Pythagorean triplet so

2n=4

n=2

1st member=n²-1

2²-1

4-1=3

3rd member=n²+1

2²+1

4+1=5
