Iona and Harris are looking for another puzzle in their book. Iona loves shape puzzles.
Harris thinks the answer to the question is 26 but Iona thinks Harris is wrong. Who is right and why?
When looking for triangles, Harris spotted lots of other shapes. How many different shapes can you find? Look carefully, not all shapes are obvious at first glance!
The puzzle contains more shapes than triangles as you’ve probably noticed – what do you know about these shapes – for example, their names, how many lines they have, are they symmetrical? What else?
