Common misconception
Pupils might get confused by shapes which are almost polygons - for example, one of the lines is slightly curved - or almost regular - for example, one side is slightly longer than the others.
These are either not polygons or are irregular polygons. Ensure pupils are clear about that. Examples and non-examples are given, including 'almost' examples. You may wish to include more and display these in your Maths environment.
