2D Shape Attributes Worksheet for identifying shapes, their names, sides, and corners.

The task is to identify the names of the 2D shapes shown in the image and determine how many sides and corners each shape has. Let's solve this step by step:

Step 1: Identify the Shapes

The shapes in the image are:
1. Triangle
2. Circle
3. Square
4. Rectangle
5. Diamond (Rhombus)
6. Heart
7. Oval

Step 2: Determine the Number of Sides and Corners for Each Shape

#### 1. Triangle
- Name: Triangle
- Sides: 3
- Corners: 3

#### 2. Circle
- Name: Circle
- Sides: 0 (A circle has a curved boundary, not straight sides)
- Corners: 0 (A circle has no corners)

#### 3. Square
- Name: Square
- Sides: 4
- Corners: 4

#### 4. Rectangle
- Name: Rectangle
- Sides: 4
- Corners: 4

#### 5. Diamond (Rhombus)
- Name: Diamond (Rhombus)
- Sides: 4
- Corners: 4

#### 6. Heart
- Name: Heart
- Sides: 2 (The heart shape can be considered to have two curved sides)
- Corners: 0 (The heart shape has no sharp corners)

#### 7. Oval
- Name: Oval
- Sides: 0 (An oval has a curved boundary, not straight sides)
- Corners: 0 (An oval has no corners)

Step 3: Fill in the Table

Here is the completed table:

| Shape | Name | How many sides? | How many corners? |
|-------------|-------------|-----------------|-------------------|
| △ | Triangle | 3 | 3 |
| ○ | Circle | 0 | 0 |
| □ | Square | 4 | 4 |
| └───┘ | Rectangle | 4 | 4 |
| ◇ | Diamond | 4 | 4 |
| ♥ | Heart | 2 | 0 |
| ⬢ | Oval | 0 | 0 |

Final Answer:

\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{Shape} & \text{Name} & \text{How many sides?} & \text{How many corners?} \\
\hline
△ & \text{Triangle} & 3 & 3 \\
○ & \text{Circle} & 0 & 0 \\
□ & \text{Square} & 4 & 4 \\
└───┘ & \text{Rectangle} & 4 & 4 \\
◇ & \text{Diamond} & 4 & 4 \\
♥ & \text{Heart} & 2 & 0 \\
⬢ & \text{Oval} & 0 & 0 \\
\hline
\end{array}
