Answer:

FIRST of all if it's a Pythagorean triplet

\implies [/tex]it must be a right angled triangle ..now , we \:know \:that the \:side opposite to the largest angle is the largest side in right angled triangle it is said to be as hypotenuse .Here, we can see that 13 is the largest side so it must be hypotenuse.rest <klux>5</klux> and 12 must be base and perpendicular of the triangle now, using Pythagoras triplet[tex] \longrightarrow

(H)²=(B)²+(P)²

\implies (13)²=(12)²+(5)²

\implies 169 =144+25

\implies 169=169

L.H.S=R.H.S

hence prooved
