re: I've Got An Angle

With your line ran between the two legs, mark eight inch or other chosen increments on it for the forty-five degree marks.

When marking degree points, mark critical positions, such as 90, 72, 60, 45, 30 and 22-1/2 degrees for easy location in the future.

Using this, you can mark any angle accurately. You can use a chalk line to mark the angle, if desired.
