Did you sleep through middle school geometry?  Try the 3-4-5 triangle.   :D

Draw a pencil line 100mm from every wall on the floor or ceiling (assuming you are fitting coving or skirting to an out of square room), next draw a line from where the lines meet to where the 2 walls meet, use a sliding bevel on this line to bisect the angle

I'm confus.  What are you installing and where?  You talking about a 4 walled room with a rhomboid floor and you're fitting baseboards?  Or putting wall lining or tiles onto a wall that has walls to its left and right that are off plumb?

The short answer is a digital angle finder.  Old school would be the makeshift guide you described.
