- 1.A straight line is drawn from the centre of a circle to a point on the circle. Write down the name of this line.
- 2.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.
- 3.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.
- 4.A circle has a radius of 3 cm. Work out the diameter of the circle.
- 5.A tangent touches a circle with centre O at the point P. Q is a point on the tangent. Write down the circle fact that tells you the size of angle OPQ.
- 6.A tangent to a circle touches the circle at exactly one point, P. Work out the size of the angle between the tangent and the radius drawn to P.
- 7.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.
- 8.Every point on a circle is exactly the same distance from one particular point. Write down the name of that point.
- 9.In one circle, chord PQ is 6 cm long, chord RS is 10 cm long, chord TU is 14 cm long and chord VW is 15 cm long. Write down which of these chords lies closest to the centre of the circle.
- 10.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.
- 11.A trundle wheel has a diameter of 0.5 m. It is rolled along the ground and makes 20 complete turns. Using π = 3.14, work out the total distance rolled, in metres.
- 12.A chord divides a circle into two segments of different sizes. Write down the name given to the smaller of the two segments.
- 13.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.
- 14.The curved part of a circle's circumference, between two points on the circle, has its own name. Write down this name.
- 15.A diameter divides a circle into two equal halves. Write down the special name given to each of these two halves.
