no the triangle with sides 12cm 16 cm 18cm can't be a right angle triangle because of the Pythagoras theorem

If the given sides are of a right triangle then they should satisfy pythagoras theorem
square of hypotenuse=sum of squares of other two sides
here the largest side is the hypotenuse.
18square=16square+12square
324=256+144
this condition is not satisfied and hence 18cm,16cm,12cm are not vertices of a right triangle.
