I tried several things, but none worked as it should. How to move vector(points) coordinates, for a certain angle that I calculated!
I calculated $\beta = 88.7^\circ$.
I'd like to expand/skew vectors $DA$ and $DC$, to get perpendicular vectors($90^\circ$)(in my case for $1.3^\circ$). How to calculate that (I need to get coordinates).
After that I need to "move" the rectangle, to be perpendicular to the coordinate system (which is in the picture case the blue/black rectangle)
I don't need the result, I'd like to know how this is calculated.
