1. What are compasses?
Compasses are a device for drawing circles. (They have a point on one end and a pencil or lead at the other.)
They are sometimes called a compass or a pair of compasses.
2. Can you use a ruler or protractor to draw constructions?
Constructions are usually done just using compasses and a ruler (straight edge) but often a protractor and a ruler will need to be used for measuring one or more angles and sides.
A question in a test or exam will usually state the equipment that can be used.
3. What is a protractor?
A protractor is a device for measuring or drawing angles. The most common type is a small piece of plastic in a semi-circular shape.
