Try continuing these patterns made from triangles. Can you create
your own repeating pattern?
Watch this "Notes on a Triangle" film. Can you recreate parts of
the film using cut-out triangles?
This practical problem challenges you to create shapes and patterns
with two different types of triangle. You could even try
What do these two triangles have in common? How are they related?
In how many ways can you fit two of these yellow triangles
together? Can you predict the number of ways two blue triangles can
be fitted together?
This problem invites you to build 3D shapes using two different
triangles. Can you make the shapes from the pictures?
Many of you found some good ways of labelling the underwater steps
in this challenge.
