More Venn Diagrams

Consider the polygons below: This diagram shows how these four polygons can be grouped into the categories Concave and Not Concave.


Problem B1
Make a diagram to show how these same four polygons can be grouped into the categories Line Symmetry and Not Concave. Use a circle to represent each category. Note 4

The circles need to overlap. Why? What goes in the middle? Close Tip
