Length and angle of an angled line

Hi

I am working on a project that has lots of angled lines. I don't see a way to specify the length of an angled line or to find out the length (or angle) of a selected line. The property manager gives me the X and Y coordinates for the nodes, the X and Y lengths, and the coordinates of the centre point. I can grab the line and swing it fully vertical or horizontal, read the length and then undo the move but that is quite time consuming. Is there a better way?

I would expect the same kind of functionality that you get for a box - you have its angle and dimensions regardless of the orientation.
