I am sorry but it is not true! It would prpose to speak not about "normal" but "standard" lens. The definition of a "standard" lens would be: the "length" of the "standard" lens ( focusdistance) is approximately equal to the diagonal of the frame (not twice), because in that case would be the angle approx. 53 grades, which is the "standard" so to speak.
