What tool is used to draw circles and arcs?

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 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 use of a pair of dividers?

A pair of dividers is a tool used in various fields such as woodworking, metalworking, and drafting to accurately measure distances and create precise layouts. They consist of two sharp points attached to a hinge which can be adjusted to set a specific distance. Dividers are commonly used to scribe arcs, mark out equal distances, and transfer measurements from one location to another with precision.


What tool do use to layout a 90 degrees angle?

If available, a protractor or a right drawing triangle can be used. If restricted to ruler and compass, a right angle can also be constructed to a given line segment by drawing a circle, with a radius less than the length of the line segment but more than half that length, with each end of the line segment as a center and connecting the two points of intersection of the two circles above and below the line. The line connecting to two intersections of these circles will form as right angle to the line segment.
