Keywords
Pair of compasses - A pair of compasses is a tool which can be used to draw circles and arcs. A pair of compasses is sometimes referred to just as a compass.
Radius - The radius is any line segment that joins the centre of a circle to any point on its circumference.
Congruent - If one shape can fit exactly on top of another using rotation, reflection or translation, then the shapes are congruent.

Common misconception
Pupils read from the incorrect values on the protractor.
Encourage pupils to consider the type of angle they are drawing. If it is an acute angle, will it really measure 122°?
