### What is a compass pencil?

: a compass with a pencil on one leg for use in drawing.

### Why is it necessary to attach a pencil to a compass?

The pencil lead draws the circle on a particular paper or material. The better quality compass, made of metal, has its piece of pencil lead specially sharpened to a "chisel edge" shape, rather than to a point.

### How do you draw a protractor step by step?

Fold a triangle with one edge from the upper left corner of the paper to the bottom center of the paper. This will create a 60º angle. Create the same fold from the right side to create a 120º angle. Mark these angles on your protractor.

### How is a protractor used?

A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Some protractors are simple half-discs. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle.
