How do you find the center of a circle using a carpenter's square?
Answer:
Any straight edge will guide you to draw a "+" and move it around until each arm is equidistance from the edges. This has worked for me and its the only way I know. There may very well be a formula for your question but I haven't bothered to look for it. A carpenter's square, properly stamped, has enough information on it to construct a high-rise complex so there are a few things to learn.
