The tool commonly used to draw circles and arcs is called a **compass**. Here are some details about it:
- **Compass**: This is a drawing instrument that consists of two legs, one with a pointed end to anchor the tool at the center of the circle or arc, and the other with a pencil or pen to draw the circle or arc. The distance between the legs can be adjusted to change the radius of the circle or arc being drawn.
Additionally, for more precise or larger scale drawings, other tools and devices might be used:
-
**Beam Compass**: Used for drawing larger circles or arcs, it has a beam or rod with a sliding holder for the pencil or pen.
-
**Protractor**: While not used to draw circles, a protractor is often used to measure angles and can assist in the construction of arcs.
-
**Drafting Tools and Software**: In technical drawing and CAD (computer-aided design), software tools can be used to create precise circles and arcs digitally.

What is a geometric tool used to draw circles and arcs?
A compass
What is a instrument used to construct circles and arcs circles in math?
It is "a pair of compasses" - usually called a compass.
What is an arc in math?
An arc is a portion of the circumference of a circle, and the circumference of a circle is the distance round a circle. So an arc looks like a semicircle, it is part of the circumference. Arcs are often used in constructions, for example if you were asked to draw an angle of 60 degrees without a protractor you would draw arcs following a special method. Arcs are drawn using a tool called a pair of compasses.
What is the a compass in math?
In math a compass is an object used to draw accurate circles and arcs (parts of circles, or curves). In math, a compass is something that makes a circle and it also measures circumference. How to make a circle: A compass either has led in it or you stick a pencil in it, but it depends on what kind of compass it is. If you want to make a big circle, you expand the 2 sides. when you get it to the size you want, you stick it on paper and twirl it around. It may not be a perfect circle but it most likely will be close.
How can a compass help in math?
A compass can be used to calculate distance by angle and to help draw circles as well as finding the radius, diameter, and circumference of the circle.
