Question

9,12,18 Pythagorean triplets​

Answer 1

Step-by-step explanation:

(18)² = (9)² + (12)²

324 = 81 + 144

324 ≠ 225

no it is not a Pythagorean triplet

Answer 2

Answer:

Step-by-step explanation:

let

perpendicular=9

base=12

hypotenuse=18

we know that Pythagoras theorem states that

(perpendicular)²+(base)²=(hypotenuse)²

LHS= (perpendicular)²+(base)²

(9)²+(8)²

=81+144

=225

RHS=(hypotenuse)²

=(18)²

=324

LHS≠RHS

hence 9, 12, 18 are not Pythagorean triplets
