Step-by-step explanation:
[tex]19^{2} + 180^{2} = 361 + 32400 = 327619\\...(1) \\ \\ 181^{2} = 32761...(2) \\ \\ from \: (1) \: and \: (2) \\ 19^{2} + 180^{2} =181^{2} \\ \\ \therefore \: 19 \: \: 180 \: \: and \: \: 181 \: are \: sides \: of \: \\ right \: triangle.[/tex]
Similarly 33, 56 and 65 are also sides of right triangle.
