Question

Which of the following are Pythagorean triplets?
(i) (2, 2, 2) (ii) (3, 4, 5) (iii) (9, 12, 15
answer it correct and I will mark as BRAINLIESTanswer bcoz u are importantforme becoz u solved my question​

Answer 1

Step-by-step explanation:

A "Pythagorean Triplet" is a set of positive integers, a, b and c that fits the rule:

∴ a² + b² = c²

(i)

Since 2² = 2² + 2²

=> 4 = 4 + 4

=> 4 = 8

This is not a Pythagoras triplet.

(ii)

5² = 3² + 4²

⇒ 25 = 25

So, this is a Pythagorean triplet.

(iii)

15² = 9² + 12²

⇒ 225 = 81 + 144

⇒ 225 = 225

So, this is a Pythagorean triplet.

Hope it helps!

Answer 2

Answer: (ii) (3,4,5) & (9,12,15)

Step-by-step explanation:

You can check them by applying Pythagoras therom.

Let me do one for you.

(ii) (3,4,5)

(3)^2 = 9 , (4)^2 = 16 & (5)^2 = 25

And,

9 + 16 = 25

Hence it's a Pythagoras triplet.

Similarly you can check out the remaining.

But only option (ii) & (iii) will satisfy the Pythagoras therom.

You can check for option (iii) yourself.
