How to find an angle on this protractor?

[bob stotts]

I just bought a 7 inch starrett miter saw protractor and run into this problem from the git go. I have a outside corner with one side that is long and the other is only 3 inch's long, so the protractor willn't fit around it. Does anyone with this unit have a way to use this protractor this to find the angle of this outside corner? I do have a sliding tee bevel but was hoping this would let me use it a lot less. thanks

Place a straight edge on the 3" leg so it sticks out past the long edge and measure the inside angle. Then subtract from 180. Dick B.

Dick thanks for the quick reply. Just so I know what I am doing. the angle is 44 is that what I subtract from 180 or do I not realy understand this, to get both angles. thanks

A picture would be worth........ Take a piece of paper or card board and cut it to the 136* angle and see if it fits. The straight edge is 180* so the remainder is 136#. That's a pretty flat angle. Try the paper. Dick B.

Bob,
I used a contour gauge to transfer the angle to a larger sheet of paper, then I use a straight edge to extend the lines.

I laid the Starrett job site protractor to measure the extended lines then.
