Lesson details
Key learning points
- Congruent shapes can be used to investigate rotational symmetry.
- The centre of rotation is the centre of the shape.
- You must be careful not to count the starting point twice.
Keywords
Rotational symmetry - Rotational symmetry describes when a shape appears the same after some rotation. The order of rotational symmetry is the number of times the image appears the same as the object in one full turn.
Common misconception
When rotating a shape to count its order of rotational symmetry, pupils may count the starting position twice: once at the start and then again at the end of the full turn.
Encourage pupils to be consistent with when they count the starting position, either always counting it before they begin rotating the shape or always counting it at the end of the full turn.
