I have a set of points that comprise the trajectories of a jagged, wriggling line. I need to rotate the complete line without shrinking or dilating the height or length. I need both algorithm and toolbox suggestions. Thank you.

More Information: I neglected to say that the trajectory should be assumed to start at 0,0 and would need to be rotated about that point.

You also neglected to attach your data so we can't do anything with them. So my answer below doesn't change. Good luck though.

Use the rotation matrix: https://en.wikipedia.org/wiki/Rotation_matrix See attached demo where I rotate a set of points making up an ellipse.
