- 2.Write down the term for the distance all the way around the edge of a circle.
- 3.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 4.A cyclist rides around a perfectly circular track with centre O. At every moment of the ride, the distance from O to the cyclist is exactly the same. Which term names this fixed distance?
- 5.A sector of a circle is bounded by two straight edges and one curved edge. Write down the mathematical term for each of the two straight edges.
- 6.Two points on a circle divide its circumference into two arcs of different lengths. Write down the name given to the shorter of the two arcs.
- 7.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
- 8.A circle has centre O. PQ, RS and TU are three chords of the circle, and only one of them passes through O. Write down what this tells you about that chord.
- 9.A circle has circumference 31.4 cm. Using π = 3.14, work out the radius of the circle.
- 10.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 11.A chord is drawn across a circle, dividing the circle into two regions. Write down the name of one of these two regions.

- 13.A chord divides a circle into two regions, one larger than the other. Write down the term used for the smaller of these two regions.
- 14.A sector of a circle has an angle of 90° at the centre. Write down what fraction of the whole circle this sector represents.
- 15.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
