Learning Goal
Part of: Classify two-dimensional figures into categories based on their properties — 1 of 2 cluster items
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category
**5.G.B.3**: Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

What you'll learn
- Explain that when a category of two-dimensional figures has a specific attribute, every subcategory of that category also has that attribute
- Identify the category-subcategory relationships among quadrilaterals (quadrilaterals, parallelograms, rectangles, rhombuses, squares)
- Use deductive reasoning to determine whether a given property applies to a subcategory by tracing it from the parent category
- Justify why "all squares are rectangles" is true while "all rectangles are squares" is false, using attribute inheritance
- Construct or interpret a diagram (Venn diagram or tree diagram) that shows how categories of two-dimensional figures nest inside one another
