I've been struggling to this for some time now and can't really find the answer on the web, but: sometimes when I want to set circle inside of an angle, it just throws it out on the wrong side. Like on the photo below: I wanted to insert circle between two lines and trim it (so it would look like red arc at the end), where I choose 2 lines (TTR command) where the green stars are, but the circle got dropped on the other side.
What's going wrong here, what's the matter? I had my mouse (while entering radius) on the right side of the vertical line.
