1. Firstly, Draw a chord between two points.
Label the two points A and B.
2.Use a compass to draw two overlapping circles.
a) The circles should be the exact same size. Make A the center of one circle, and B the center of the other. Space the two circles so that they overlap like a Venn diagram.
3. Draw a vertical line through the two points at which the circles intersect.
a) There will be a point at the top and a point at the bottom of the "Venn diagram" space created between the overlap of the circles. Use a ruler to make sure that the line protrudes straight through these points.
Finally, label the two points (C and D) at which this new line crosses the rim of the original circle. This line marks the diameter of the original circle.
4. Erase the two overlapping circles.
5.Sketch two new circles.
a) Use your compass to draw two equal circles: one with the point C at its center, and one with the point D.
These circles, too, should overlap like a Venn diagram.
Remember: C and D are the points at which the vertical line intersects the main circle.
6. Draw a line through the points at which these new circles intersect.
a) line is the second diameter of your original circle, and it should be exactly perpendicular to the first diameter line
7.Find the center.
a) The intersection point of the two straight diameter lines is the exact center of the circle!
8.Mark this center point for reference.
