Task:

Write the name and number of lines (sides) for each polygon.

We will go through each shape one by one:

---

#### a. Triangle
- Shape: A three-sided polygon.
- Name: Triangle
- Number of lines (sides): 3

✔ *Answer:*
Name: Triangle
Number of lines: 3

---

#### b. Rectangle
- Shape: A four-sided polygon with opposite sides equal and all angles 90°.
- Name: Rectangle
- Number of lines (sides): 4

✔ *Answer:*
Name: Rectangle
Number of lines: 4

---

#### c. Square
- Shape: A four-sided polygon with all sides equal and all angles 90°.
- Name: Square
- Number of lines (sides): 4

✔ *Answer:*
Name: Square
Number of lines: 4

> Note: A square is a special type of rectangle, but here it's shown as a separate shape.

---

#### d. Hexagon
- Shape: A six-sided polygon.
- Name: Hexagon
- Number of lines (sides): 6

✔ *Answer:*
Name: Hexagon
Number of lines: 6

---

#### e. Octagon
- Shape: An eight-sided polygon.
- Name: Octagon
- Number of lines (sides): 8

✔ *Answer:*
Name: Octagon
Number of lines: 8

---

#### f. Rhombus
- Shape: A four-sided polygon with all sides equal (but not necessarily right angles).
- Name: Rhombus
- Number of lines (sides): 4

✔ *Answer:*
Name: Rhombus
Number of lines: 4

---

#### g. Octagon
- Shape: Again, an eight-sided polygon.
- Name: Octagon
- Number of lines (sides): 8

✔ *Answer:*
Name: Octagon
Number of lines: 8

---

#### h. Pentagon
- Shape: A five-sided polygon.
- Name: Pentagon
- Number of lines (sides): 5

✔ *Answer:*
Name: Pentagon
Number of lines: 5

---

✔ Final Answers Summary:

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

🔍 Explanation:

Polygons are named based on the number of their sides:
- Tri- = 3 → Triangle
- Quad- = 4 → Quadrilateral (Rectangle, Square, Rhombus)
- Penta- = 5 → Pentagon
- Hexa- = 6 → Hexagon
- Octa- = 8 → Octagon

Each side of a polygon is a straight line segment, so counting the sides gives the number of lines.
