Group all the red figures into 1 group and all the quadrilaterals into another group. Quadrilaterals
Red figures
Find the figures that fit in both categories.
Place the figures in the Venn diagram. Place the figures from in the
intersecting part of the circles.
Relationships among sets of objects can be easily seen when using a Venn diagram.
