What is the tool called that will illustrate a circle?

I need to buy one, but I can't remember the name. You angle your pencil and rotate it around an axis.

The compass is an adjustable v shaped tool used often in geometry to construct a perfect circle. This tool is often paired with other geometry tools such as protractors.

You're probably thinking of a drafting compass (as opposed to a navigational compass), the device with two ends on a hinged angle, one end having a spike, the other end having a sleeve for a pen or pencil.

The item you are thinking of is a protractor. You should be able to find one at any store that carries school supplies.

The tool you need is called a compass. Usually they are purchased as part of a geometry set, rather than on their own.
