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).
