CPM Homework Help : CCG Problem 2-12

Larry saw Javon’s incomplete Venn diagram at right, and he wants to finish it. However, he does not know the condition that each circle represents. Find a possible label for each circle, and place two more shapes into the diagram.

Venn diagram with 2 circles that overlap, each labeled with a question mark. In the left circle but not in the overlapping portion, is a triangle where each side has 1 tick mark. In the overlapping section, is a quadrilateral where each side has 1 tick mark.

Hint:

What do the two figures have in common? That trait is the condition the left circle represents.

More help:

What is a difference between the two shapes? The trait unique to the figure in the middle of the Venn diagram is the condition the right circle represents.

Possible Answer:

The left circle represents equilateral and the right circle represents quadrilateral.

Two possible shapes:

A pentagon where all 5 sides have 1 tick mark.

A 4 sided figure where two opposite sides have 1 tick mark each and the other two opposite sides have 2 tick marks each.
