Down
- 1. a closed, 2D shape with at least 3 straight sides; sides do not cross each other
- 2. a flat surface formed by two perpendicular number lines called axes
- 5. a system of ranking shapes into categories and subcategories based on their properties; for example, all squares are rectangles, but not all rectangles are squares
