- 1.A line segment joins two points on the circumference of a circle, without necessarily passing through the centre. Write down the general term for this line segment.
- 2.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.
- 3.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 4.A sector of a circle has an angle of 90° at the centre. Write down what fraction of the whole circle this sector represents.
- 5.A straight line touches the edge of a circle at exactly one point and does not cross into the circle at all. Write down the term for this line.
- 6.Two circles are drawn with the same centre but different radii. Write down the term used to describe this pair of circles.
- 7.A circle is drawn on a page. Write down how many radii can be drawn in the circle.
- 8.Every diameter of a circle is an example of a more general type of straight line joining two points on the circle. Which term names that more general type of line?
- 9.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 10.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?
- 11.A circle has two straight radii drawn from the centre to the edge, together with the arc between them. Write down the name of the region enclosed by these two radii and the arc.
- 12.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.
- 13.A circle has diameter 10 cm. Using π = 3.14, work out the circumference of the circle.
- 14.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
- 15.Write down the term for the distance all the way around the edge of a circle.
