Finding an angle of a wall

[crea2k]

Hi, im trying to re create the layout of an area outside my house for some planning documents and can measure the wall lengths just fine using a tape measure to the mm, but cant work out how to work out the angles of the walls. Is there a tool I can use for this, I can put in the corners and give the angle of each of the walls ?.

Im guessing this will work ? :

You mean like trigonometry??

Can I use the double skin wall as an external wall ok, is there any building controls that say that I cant use it as a garage / shed wall, with it not having cavity wall insulation, not that I need it as its going to be a shed, but wasn't sure if building control was really backwards in that respect ?.

lol yes I figured that out after I had posted it, as the planning drawing software only asks for lengths and works out the angle using that, I was over thinking it all !.

Or if it is not acceptable to code I suppose I could just construct blockwork on the inside, and then have insulation between the blockwork and the existing wall ?.
