A. $$5^2$$ = $$3^2$$ + $$4^2$$

B. $$13^2$$ = $$12^2$$ + $$5^2$$

C. $$17^2$$ = $$15^2$$ + $$8^2$$

D. $$18^2$$ $$not$$ = $$12^2$$ + $$15^2$$

E. $$15^2$$ = $$12^2$$ + $$9^2$$

option A, B , C and E satisfy the pythagoras theorem which is $$one side^2$$ + $$another side ^2$$ = $$hypotenuse^2$$
option D doesn't satisfy this theorem
