Area
Key Stage: 4 ★★
What are the areas of these equilateral triangles in terms of the smallest equilateral triangle? What if the triangles are tilted?
This problem challenges understandings concerning area on the way to working in a context which leads to non-linear sequences that need explanation. Learners will need to use their visualising skills to help them to create equilateral triangles and find their areas.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
