      Mark three points anywhere on the circumference of the circle. Designate these points A, B and C. It doesn't matter where you put these points, but the farther they are from each other, the more accurate your calculations will be

      Draw a line connecting points A and B. Call this line AB. Do the same with points B and C to create line BC.

      Find the center of line AB and BC. You can either measure the distance and divide it in half or use geometry and bisect the lines. You can use a compass set at a distance greater than half the length of the line segment and make arcs above and below the line segment. Do this from both endpoints to form points above and below the line segment, then connect these points to divide the line segment in half. Mark these middle points D and E.

      Draw perpendicular lines from points D and E using the compass technique or using a protractor to find a 90-degree angle. Where these lines intersect is the center of the circle.

Tips & Warnings
  • You can check that you have found the center of the circle. Simply measure from the point you found to the edge of the circle. Pick a few different points. If they are all the same distance, you have found the center.

There's no fun in playing it safe. Why not try something a little unhinged?
