All four angles must be 90 degrees and the two parallel sides must have different dimension from the other two.
Considering it mathematically string is nothing but a line... So it only has one dimension that is length.. considering it physically.. It is nothing but a metal ROD.. with a given Diameter so it has three degrees of freedom hence it is a 3D structure..

A tri-atomic molecule should have 3 vibrational degrees of freedom (one for each "end" atom vibrating on its bond with the central atom and one for the flexing of the bonds like scissors opening and closing). If it is non-linear, it should also have a three rotational degrees of freedom. All molecules (including a triatomic one) will have 3 degrees of freedom for translational motion. All totaled, it will have 3+3+3 = 9 degrees of freedom. Note that this does not address the question of independence of the degrees of freedom - for example - if the two "end" atoms are identical, not all the rotational degrees of freedom are independent.

no, it has two degrees of freedom. because it can rotate through X,Y plane.

Number all the structural degrees of freedom in your truss. In a 2D (planar) truss, each joint can have a maximum of two degrees of freedom: one in the global X-direction and one in the global Y -direction. If a degree of freedom is restrained by a reaction, then it doesn't get a number.
