Identify and count the sides of regular polygons in this educational worksheet.

Let's solve the Regular Polygon Worksheet step by step.

We are asked to:
- Identify the name of each polygon.
- Count the number of sides.

🔹 Understanding Regular Polygons

A regular polygon has:
- All sides equal in length.
- All interior angles equal.

But note: The worksheet says "Identify the polygon", so we'll use standard names based on the number of sides, even if not all shapes shown are regular (e.g., some might be irregular).

---

Now let’s go through each shape:

---

1.

Shape: Square
- It has 4 equal sides and 4 right angles.
✔ Name: Square
✔ Number of sides: 4

---

2.

Shape: Triangle
- It has 3 sides.
✔ Name: Triangle
✔ Number of sides: 3

---

3.

Shape: Pentagon
- A five-sided polygon.
✔ Name: Pentagon
✔ Number of sides: 5

---

4.

Shape: Rectangle
- Has 4 sides, opposite sides equal and parallel.
Note: This is not a regular polygon unless it's a square. But the question asks for the name, so we call it a rectangle.
✔ Name: Rectangle
✔ Number of sides: 4

---

5.

Shape: Trapezoid
- A quadrilateral with one pair of parallel sides.
✔ Name: Trapezoid
✔ Number of sides: 4

---

6.

Shape: Irregular Quadrilateral
- 4 sides, but not a rectangle, square, or trapezoid (based on appearance).
It looks like a kite or an irregular quadrilateral.
But since no specific details are given, we can just call it a quadrilateral.
✔ Name: Quadrilateral
✔ Number of sides: 4

> Note: If it's a kite or rhombus, that would require more symmetry. But without clear markings, "quadrilateral" is safest.

---

7.

Shape: Hexagon
- Six sides, and appears regular (all sides equal, symmetric).
✔ Name: Hexagon
✔ Number of sides: 6

---

8.

Shape: Octagon
- Eight sides, regular-looking.
✔ Name: Octagon
✔ Number of sides: 8

---

✔ Final Answers:

| No | Name | Number of Sides |
|----|---------------|------------------|
| 1 | Square | 4 |
| 2 | Triangle | 3 |
| 3 | Pentagon | 5 |
| 4 | Rectangle | 4 |
| 5 | Trapezoid | 4 |
| 6 | Quadrilateral | 4 |
| 7 | Hexagon | 6 |
| 8 | Octagon | 8 |

📝 Notes:

- Shapes 1–3 and 7–8 are regular polygons (equal sides and angles).
- Shapes 4–6 are quadrilaterals, but only 1 and 4 are regular (square), others are irregular.

Even though the title says "Regular Polygon Worksheet", not all shapes shown are regular — so we identify them by their general names.
