Is this set of numbers a Pythagorean triple? yes or no

Answer:- No.

Explanation :-

Substitute these numbers in pythagoras theorem to check if the set of numbers is a pythagorean triplet.

Pythagoras theorem :- sq. of hypotenuse (longest side) is equal to the sum of sq.s of other two sides.

Here,

hypotenuse = 12 (as it is the longest side)

and other two sides are 6 and 9.

> 6^2 + 9^2 = 12^2

> 36 + 81 = 144

> 117 = 144

Since, LHS is not equal to RHS, this set of numbers is not a pythagorean triplet.

I believe it is nothing because 66 divided by 11 is 6, an even number. Because 6 times 11 is 66. Therefore, making it to where 6 is the answer to 66 divided by 11 and there is no decimal so it shouldn't repeat.
