Finding the Center of a Circle with a Compass

How can you find the center of a circle? You can use a compass and a ruler. This video shows you how to find the center of a circle using a simple geometric construct, and all you need is a compass and a ruler.

Other way using paper. Mark the circle on paper by tracing the original disk and cut the paper disk out. Fold the paper disk in half and do it two roughly perpendicular directions. The creases will intersect at the center.

I am an Linoleum layer. Make three random marks that are not close to each other on the outside of the circle. Adjust the center leg of a pair of dividers so that the other leg touches all three marks that's your center.
