Question

(4 9 12) is a paythagorean triplet or not​

Answer 1

Answer:

Just use the Pythagorean theorem ${h}^{2} = {p}^{2} + {b}^{2}$ , Put the 12 as hypotenuse as it is the highest number among those numbers and it's your choice whether you wanna put 4 as base or a perpendicular. Plug those values and find out if those numbers satisfy the Pythagorean theorem or not. If it satisfies, you can say they are Pythagorean triplet. If it doesn't then you can simply say they are not Pythagorean triplet. Try it , once !

Answer 2

Answer:

let a triangle ABC and AB is the largest side of triangle

by Pythagoreas theorem

(AB)^2=(BC)^2+(AC)^2

LHS=12^2

=144

RHS=9^2+4^2

=81+16

=97

Hence LHS is not equal to RHS

so it is not a Pythagorean triplet
