Venn and Tree Diagrams for Geometry

“A Venn diagram sorts shapes based on whether they have "Right Angles" and "Equal Sides". How many shapes have both right angles and equal sides if there are 2 shapes in the overlapping section of the Venn diagram? A Venn diagram sorts shapes based on whether they have "Parallel Lines" and "Lines of Symmetry". How many shapes have parallel lines but do not have lines of symmetry if there is 1 shape only in the "Parallel Lines" section of the Venn diagram (not overlapping)? A Venn diagram sorts shapes based on whether they have "4 Sides" and "Right Angles". How many shapes have either 4 sides or right angles (or both) if there are 2 shapes in the "4 Sides" section, 1 shape in the "Right Angles" section, and 3 shapes in the overlapping section?”
