R, S, and T are points with RT = 2RS. Which of the following could be true? (more than one choice is a possible answer)

I. R, S, and T are the vertices of a right triangle.
II. R, S, and T are three of the vertices of a square.
III. R, S, and T all lie on the circumference of a circle.

The right triangle is YES possible with R, S, and T as vertices and hence, R, S, and T all may lie on the circumference of a circle as well; but the given specification cannot make R, S, and T as three of the vertices of a square.

Ooops! Its true Sanju is right

Somehow, i wrongly assumed that triangule would be made out of 1 side RT and 2 sides RS, and that would not be possible.
