Construct a circle with a compass and then draw a straight line through its centre

To draw a circle with a compass, first set the distance between the point and the pencil of the compass using a ruler. This distance is the radius. Now, place the point on the paper where you want the center of the circle. Spin the compass around the point, lightly dragging the pencil on the paper, and you will have a circle.

The only way a compass can be used to create a circle is if you draw round it, because a compass is actually a navigational instrument which shows direction. If you're out in the woods, for example, you use a compass to show you which direction you need to head in. A pair of compasses can be used to construct, or draw, a circle of any size, up to the maximum reach of the "arms".
