Students identify polygons by circling correct shapes and matching polygon types to the number of sides.

Let's solve this "Identifying Polygons Worksheet" step by step.

🔹 Part 1: Circle the shapes that are polygons

#### ✔ What is a polygon?
A polygon is a closed 2D shape made up of straight line segments (no curves). It must have:
- Straight sides
- Closed shape
- No gaps or curves

Now, let’s examine each shape in the image:

1. Triangle – ✔ Yes (3 straight sides, closed)
2. Rectangle – ✔ Yes (4 straight sides, closed)
3. Pentagon – ✔ Yes (5 straight sides, closed)
4. Circle – ✘ No (it has a curve, not straight sides)
5. Arrow-shaped figure (with a pointed end) – ✘ No (has curved edges or non-straight lines? Actually, in this case, it appears to be made of straight lines but with an open side — wait, look closely: it's closed and made of straight lines → Yes, it is a polygon)
- Wait! Let's clarify: The arrow shape has straight lines and is closed → ✔ It is a polygon
6. Square – ✔ Yes (4 equal straight sides)
7. Trapezoid – ✔ Yes (4 straight sides, closed)
8. Diamond (rhombus) – ✔ Yes (4 straight sides, closed)
9. Hexagon – ✔ Yes (6 straight sides)
10. Parallelogram – ✔ Yes (4 straight sides)
11. Arrow shape (right-pointing) – ✔ Yes (made of straight lines, closed)
12. Rhombus (diamond) – ✔ Yes (same as above)

Wait — we need to check each one carefully.

Let’s go row by row:

---

#### Row 1:
1. Triangle → ✔ Polygon
2. Rectangle → ✔ Polygon
3. Pentagon → ✔ Polygon
4. Circle → ✘ Not a polygon (curve)

#### Row 2:
5. Arrow shape (like a house with a pointy tip) → This looks like a pentagon (5 sides), all straight, closed → ✔ Polygon
6. Square → ✔ Polygon
7. Trapezoid → ✔ Polygon
8. Diamond (rhombus) → ✔ Polygon

#### Row 3:
9. Hexagon → ✔ Polygon
10. Parallelogram → ✔ Polygon
11. Right-pointing arrow → This has straight sides, closed, so yes → ✔ Polygon
12. Rhombus (diamond) → ✔ Polygon

⚠️ But wait — there are 12 shapes, and only 1 circle (the circle is the only non-polygon).

So, only the circle is NOT a polygon.

✔ So, circle all except the circle.

> 🟩 Answer for Part 1: Circle all shapes EXCEPT the circle.

🔹 Part 2: Circle the appropriate number of sides each type of polygon has

We are given a table with polygon names and numbers from 2 to 8. We need to circle the correct number of sides.

| Shape | Number of Sides |
|-------------|-----------------|
| Triangle | 3 |
| Rectangle | 4 |
| Square | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
| Heptagon | 7 |

Now, fill in the table:

1. Triangle → circle 3
2. Rectangle → circle 4
3. Square → circle 4
4. Pentagon → circle 5
5. Hexagon → circle 6
6. Heptagon → circle 7

> 🟩 Answer for Part 2:
>
> - Triangle → ✔ 3
> - Rectangle → ✔ 4
> - Square → ✔ 4
> - Pentagon → ✔ 5
> - Hexagon → ✔ 6
> - Heptagon → ✔ 7

✔ Final Answers:

#### Part 1: Circle the polygons
- Circle all shapes except the circle.
- So, do not circle the circle; circle the other 11 shapes.

#### Part 2: Number of sides
| Shape | Correct Answer |
|-------------|----------------|
| Triangle | 3 |
| Rectangle | 4 |
| Square | 4 |
| Pentagon | 5 |
| Hexagon | 6 |
| Heptagon | 7 |

🔍 Summary of Key Concepts:

- Polygons must be closed and made of straight line segments.
- Circles are not polygons because they are curved.
- All other shapes shown (triangles, rectangles, pentagons, etc.) are polygons.
