[tex] \sf \underline \pink{pythagorean \: triplets : }[/tex]
The length of sides of a triangle follows pythagorean theorem that means which forms a right angled triangle are called pythagorean triplets.
( LONGEST SIDE)² =(ONE SIDE)²+(OTHER SIDE)²
[tex] \bf \underline{solution}[/tex]
(i) (14,48,50)
Here 50²=(14)²+(48)
It represents right angled triangle
so these are pythagorean triplets
(ii) (20,98,101)
Here 101² is not equal to 98²+20²
So not pythagorean triplets.
