What other relationships can be described using Venn diagrams? Use this tool
to explore many different geometric properties and shapes.
Select the rule "All sides are congruent" from the orange Select a rule box
and "All angles are congruent" from the green Select a rule box. This will draw
two overlapping ovals on your screen called a Venn diagram, creating four
You should now have four shapes in each of the four regions of your work
area. Click the Checkmark button at the bottom to see if you've correctly placed
your shapes. If any are incorrect, try to move them to the correct region and
find a different shape that might belong in the empty region. Keep checking your
answers until all four regions have a shape.
Looking at the shapes in your work area, what do they have in common? How are
Try moving the remaining shapes into the correct region. Check your answers
as you work. When you are finished, write some true mathematical statements
about your Venn diagram, and then clear the work area and try this activity with
two other rules.
