Lesson details
Key learning points
- A pair of compasses can be used to draw circle with a particular radius.
- All the points on the circle will be the same distance from the centre.
- The centre of a circle is the point that is the same distance from every point on the circle.
- The collection of points an equal distance from a given point form a circle.
Keywords
Fixed point - A fixed point is a point that does not change or move.
Circumference - The circumference of a circle is the perimeter of the circle.
Arc - An arc is part of a curve. An arc of a circle is part of the circle’s circumference.
Equidistant - Points A and B are equidistant from a third point C if the distance AC is equal to the distance BC.
Common misconception
During tasks, pupils may use a ruler to draw or check whether points are equidistant from a centre.
While the tasks could be completed with a ruler, it may be quicker, easier and more accurate to use a pair of compasses.
