Answer 1

THEN TELL ME WHAT TO PROVE OR SOLVE

Answer 2

Is it always true that if the right angled triangle with is also isosceles and having lengths that can be denoted in terms of a rational number, the length of its hypotenuse will always be an irrational number? Another way to look at it would be that the diagonal of a square is always irrational. Does this always hold true?
