✔ Final Answers Summary:

| Letter | Shape | Name | Number of Lines |
|--------|-------------|------------|------------------|
| a | Triangle | Triangle | 3 |
| b | Rectangle | Rectangle | 4 |
| c | Square | Square | 4 |
| d | Hexagon | Hexagon | 6 |
| e | Octagon | Octagon | 8 |
| f | Rhombus | Rhombus | 4 |
| g | Octagon | Octagon | 8 |
| h | Pentagon | Pentagon | 5 |

🔍 Explanation:

Polygons are named based on the number of sides they have:
- 3 sides → Triangle
- 4 sides → Quadrilateral (examples: square, rectangle, rhombus)
- 5 sides → Pentagon
- 6 sides → Hexagon
- 8 sides → Octagon

So, just count the sides to identify the name and number of lines.
