### **Key Definitions**

- **Parallel Sides:** Two sides are parallel if they are the same distance apart over their entire length and will never meet, no matter how far they are extended.

- **Perpendicular Sides:** Two sides are perpendicular if they intersect at a 90-degree angle.

### **Notes**

- **Regular Polygons:** These are shapes where all sides and angles are equal (e.g., regular hexagon, regular octagon). Depending on the number of sides and the orientation, some regular polygons have multiple pairs of parallel sides.

- **Irregular Polygons:** These have sides and angles that are not all equal. Their classification regarding parallel or perpendicular sides varies based on their specific geometry.

- **Non-Polygon Shapes:** Shapes like circles and ellipses do not have sides and therefore do not fall into these categories.

This categorization can help in understanding the properties of various shapes, especially in fields like geometry, design, architecture, and art.
Here are 40 geometric shapes categorized by whether they have parallel sides, perpendicular sides, both, or neither: 1. **Square, Rectangle, Rhombus, Regular Hexagon, Regular Octagon, Right Trapezoid, Oblong, Floor Tile (Square), Brick Shape, Cube (as a projection):** Have both parallel and perpendicular sides. 2. **Parallelogram, Trapezoid, Isosceles Trapezoid, Regular Hexagon, Regular Octagon, Regular Decagon, Trapezium (UK), Diamond Shape, Regular Dodecagon, Regular Heptagon:** Have parallel sides only. 3. **Right Kite, Right Arrowhead, Right Irregular Quadrilateral, L-Shape, T-Shape, Plus Sign, Cross Shape, Letters (e.g., "L", "T", "E"), Doorframe Shape, Window Frame (with muntins):** Have perpendicular sides only. 4. **Scalene Quadrilateral, General Irregular Polygon, Concave Quadrilateral, Star Polygon (Non-Regular), Irregular Hexagon, Irregular Octagon, Asymmetrical Arrow Shape, Freeform Shape (Abstract Art), Organic Shapes (e.g., Leaves, Amoeba), Irregular Star Shapes:** Have neither parallel nor perpendicular sides. This classification helps in understanding the properties of various shapes in fields like geometry, design, and architecture.
