To use this method, start by drawing a straight line across the diameter of the circle using a ruler.

Then, place the compass on one end of the diameter line and adjust its width so that it extends past the midpoint. Finally, draw an arc from both ends of the diameter line, ensuring that they intersect each other. The point of intersection is the center of the circle.

While the compass and ruler method is simple to understand and execute, it does have its limitations. One drawback is that it relies heavily on manual measurements, which can be prone to inaccuracies if not done carefully. Additionally, this method may not be suitable for larger circles where extending the compass beyond the midpoint becomes impractical or challenging.

Another traditional method for finding the center of a circle is by marking perpendicular diameters using just a ruler. Begin by placing a ruler diagonally across opposite sides of your circle so that it intersects at some point within the circumference.

Make sure to draw straight lines along these intersecting points until they touch both sides’ edge on each axis. By bisecting these lines with another pair that’s perpendicular, you’ll achieve an X shape with an intersection in its middle – this serves as your focal point.

Although this method doesn’t require any additional tools apart from a ruler, it may not provide as precise results as other techniques when dealing with irregularly shaped circles or circles with varying diameters.
