given,
ab=5cm
BC=7cm
ca=12cm
here,
by using converse of Pythagoras theorem
the big number ca=12
hence
ca(square)=ab(square)+BC(square)
12×12=5×5+7×7
144=25+49
144=74
hence it's not equal to 144
therefore it is not right angled triangle
I hope this will help

Sum of two sides of a triangle should be greater than the third side
but 5+7=12 not greater than 12
therefore triangle cannot be formed
