These are also incorrect actually! The middle one will be x(1+rt2), the same as the “circumscribing” square…for the others you will have to do (rather painful) Pythagoras applications and hence you would rarely be expected to find them in an exam scenario (which is why I left it as a homework exercise, more from the point of view of developing a comfort with geometry)
Is it right to say two shortest diagonals and one longest diagonal will make an isosceles right-angled triangle and the ratio of longest diagonal to the shortest diagonal will be √2 :1 ?
Longest – 5x^2
Middle – 2x
Sir, how to get the last one ?

Hi J,

Perfectly right, as 4 such “shortest diagonals” will form a square whose diagonal will be the “longest diagonal” here.
