Pythagorean triple is when three number satisfies .

For  3,4,5

if a=3, b=4 and c=5

then

The left hand and right hand side are satiesfied.

So, the numbers 3,4,5 are Pythagorean triple.

For  10,15,20

if a=10, b=15 and c=20

then

325400

The left hand and right hand side are not satiesfied.

So, the numbers 10,15,20 are not Pythagorean triple.

Hence, we get the set of numbers which are not Pythagorean triple that is 10,15,20.
