You can put this solution on YOUR website! If it is a right triangle then
by pythagoras theorem
25^2= 16^2+9^2
625 = 256+81
625 is not equal to 337
so it is not a right triangle

You can put this solution on YOUR website! No. A triangle with sides 9, 16, 25 is not even a triangle, since 9 + 16 equals 25, which does not satisfy the triangle inequality.

Is a triangle with sides 9 units, 16 units and 25 units a right triangle ?
~~~~~~~~~~~~~~~~~~~~~~~~~~
Good question. It is a huge trap, instead.
Notice that 9 + 16 = 25,
so the triangle inequality is violated, which means that a triangle
with the side lengths as described DOES NOT EXIST and CAN NOT EXIST.
Ha - ha - ha.
