How many triangles can you make using sticks that are 3cm, 4cm and 5cm long?



Each side can only use one stick but a triangle can use more than one stick of the same length.

 

 

You may like to use this interactivity to try out your ideas.

You could use sticks that have 4 holes, 5 holes and 6 holes to represent the 3cm, 4cm and 5cm sticks.
