Students who struggle with recognising geometrical relationships need to be provided with strategies for analysing diagrams.
- Use colour to highlight features in the diagram.
- Introduce pronumerals to indicate equal angles.
- Re-draw the diagram in a different order.
- Rotate the page to view the diagram from a different perspective.
Dynamic geometry software is an effective and engaging way to explore a problem. It also allows students to recognise different diagrammatic situations as representing the same relationship even if it appears to be unlike the ‘classic’ representation.
