Session 3, Part B: Classifying Polygons
In This Part: Properties of Polygons | Grouping Polygons | Polygon-Classification Game More Venn Diagrams
The following problems further explore the properties of polygons using Venn diagrams:
Problem B4
Use the picture of a Venn diagram below:
a.
Determine what the labels on this diagram must be.
b.
Explain why there are no polygons in the overlap of the Label 1 circle and the Label 2 circle.
c.
Explain why there are no polygons in the Label 3 circle that are not also in one of the other circles.
Problem B5
Create a diagram in which no polygons are placed in an overlapping region (that is, no polygon belongs to more than one category).
Problem B6
Create a diagram in which all of the polygons are placed either in the overlapping regions or outside the circles (that is, no polygon belongs to just one category).
