Educational worksheet for identifying 2D shapes and counting their sides.

The task is to identify and name the 2D shapes shown in the image, as well as count the number of sides for each shape. Below is the solution with explanations:

Step 1: Identify and Name Each Shape

We will analyze each shape one by one and determine its name based on its properties.

#### Top Row:
1. Shape 1 (Triangle):
- Number of Sides: 3
- Name: Triangle

2. Shape 2 (Irregular Quadrilateral):
- Number of Sides: 4
- Name: Irregular Quadrilateral (or simply Quadrilateral)

3. Shape 3 (Rectangle):
- Number of Sides: 4
- Name: Rectangle

4. Shape 4 (Square):
- Number of Sides: 4
- Name: Square

#### Bottom Row:
5. Shape 5 (Hexagon):
- Number of Sides: 6
- Name: Hexagon

6. Shape 6 (Octagon):
- Number of Sides: 8
- Name: Octagon

7. Shape 7 (Pentagon):
- Number of Sides: 5
- Name: Pentagon

8. Shape 8 (Circle):
- Number of Sides: 0 (A circle has no straight sides; it is a curved shape.)
- Name: Circle

Step 2: Fill in the Table

Using the information above, we can fill in the table as follows:

| Shape Image | Number of Sides | Name |
|-------------|-----------------|---------------|
| Triangle | 3 | Triangle |
| Irregular Quadrilateral | 4 | Irregular Quadrilateral |
| Rectangle | 4 | Rectangle |
| Square | 4 | Square |
| Hexagon | 6 | Hexagon |
| Octagon | 8 | Octagon |
| Pentagon | 5 | Pentagon |
| Circle | 0 | Circle |

Final Answer:

\[
\boxed{
\begin{array}{|c|c|c|}
\hline
\text{Shape Image} & \text{Number of Sides} & \text{Name} \\
\hline
\text{Triangle} & 3 & \text{Triangle} \\
\text{Irregular Quadrilateral} & 4 & \text{Irregular Quadrilateral} \\
\text{Rectangle} & 4 & \text{Rectangle} \\
\text{Square} & 4 & \text{Square} \\
\text{Hexagon} & 6 & \text{Hexagon} \\
\text{Octagon} & 8 & \text{Octagon} \\
\text{Pentagon} & 5 & \text{Pentagon} \\
\text{Circle} & 0 & \text{Circle} \\
\hline
\end{array}
}
\]

This completes the task!
