Is there a way to calculate angles of a shape using the exact measurements?

Hi guys, yesterday I took some measurements of this building so that I can then model it in blender. The thing is that I have all the exact length of each edge, but I don’t know how to calculate the angles so that it gives me the exact shape of the floor. The lower left angle is the only one I know for sure it is 90°. Is there any method or addon that I can use to enter the measurements so that it gives me the final shape?
Thanks for your help :slight_smile:

I’m not certain but I don’t think there is, because there could be multiple sets of angles which satisfy the given lengths. For example:

Depending on what you need it for, a good guess might be enough?

Yes, what I did was simply to eyeball it and it got very close. I only need a rough sketch of the interior, so I guess that will do. Thanks a lot :slight_smile:

Edit: nevermind lol, too much math, just use some online tool instead like this:
