This shape needs to be cut on a diagonal. The profile is an oval so just rotating the face will not work neatly. (I could do it with a rotate and a scale but what if the shape is not so nice and parallel (e.g. a compound curved shape) ?
You can easily do it in 2.49 and even string the cut in a straight line between two of the verts like so:
The red line is the cut line.
