Why do this problem?

This problem allows children to be creative in applying their knowledge of properties of triangles. It will encourage learners to talk to each other and therefore will help them become more familiar with appropriate vocabulary.

Key questions

What do you know about triangles?
How will you remember that arrangement?

Possible support

Many learners will benefit from having sticks of some kind to manipulate, for example headless matches or lolly sticks.
